Carving a Christmas D20 from Laser Crystal 

Love how this turned out bud! Fantastic work as usual :) And huge thanks for letting me show off the behind the scenes stuff!

For those interested, Cr YAG is used as a saturatable absorber Q switch. In a laser gain medium, electrons are placed in an excited state by an energy pump. Normally, some of these electrons will spontaneously decay, releasing it's energy as light. Above a certain photon density, the gain medium will intensify the photon flux and begin lazing. To control this, a saturatable absorber is used in the laser cavity. The absorber has a finite number of charge carriers that can absorb spontaneous photon emissions, which allow the laser gain medium to charge up a greater number of its electrons. Once at a high number of electrons are in an excited state the spontaneous emission becomes so large, that no more charges in the saturatable absorber are available to absorb the laser photons, causing it to become transparent to the laser light. Suddenly, the number of photos in the laser cavity is able to reach the threshold value for lasing, and the gain media dumps all of its energy at once in a powerful pulse. I know I've probably left out some important details. I'll try and answer any questions in the comments if you ask :)

This is becoming one of my favorite channels, great quality in all aspects!

This Die might honestly be one of the most beautiful ones you've done so far! It's STUNNING! The Deep Red and Bright Green just sparkle so well together in this!

Your patience and perseverance are inspiring. The calmness as you realized that a piece had chipped off and scratched a facet was impressive, cause I feel like I would have immediately panicked and been frustrated. Your videos relax me so much, and the dice are always stellar. Thanks for doing your thing and sharing it with all of us.

Coming over from Rybonators video to let you know that d20 looks so stunning, even after he covered it in smugdes 😂

Having a mild red-green colour deficiency, I cannot truly appreciate this dice and it is still a stunningly beautiful piece of art. Amazing video (as always).

Man, the final reveal is unreal. This is probably going to be among my favorites you've made. This reminds me of another lab originated stone, look up lutetium aluminum garnet, or "LuAG". Would love to see you cut a D20 from it. It has a very intense green fluorescence when exposed to blue light.

Wow. I did not expect the colors to come through so vividly after it was faceted. That is incredibly beautiful.

If you had told me a couple of years ago i’d be hooked on watch a guy make D20’s out of various stones I wouldn’t have believed you. Everything you put on YT is just beautiful man

Man, I desperately want one of these dice. They're so beautiful. Goblin brain wants shiny click clack rocks.

Holy. Shite. My jaw literally dropped. I know you mentioned that the payoff would be cool once it's polished up. That the competing red and green would be amazing. But color me ignorant cuz I had no idea how amazing it would look. Seriously just... 😯 Amazing work. And the music on the reveal... *chefs kiss*

It really is red and green at the same time. wow

As GORGEOUS as these d20s turn out every single time, I’d love to see you make a whole dice set, some bigger dice, or some out of an odd material! Greats videos nonetheless, I watch every single one as they come out.

I’m red/green colorblind and I’d love to see this in person. If nothing else, I think it would be hilarious to insist there’s nothing special about the color to everyone else.

I love this channel for the ASMR part and the soothing atmosphere while creating something beautiful. It´s nice there is still something like this left in this hectic world

As someone who does woodworking and occasionally metal working, when you said 3000 grit, then 8000… I thought, okay yeah, get that thing really nice; then you said 50,000 for the polish, and I choked on my coffee. That’s a lot of grit! But obviously, the sort of thing needed for such hard materials and such high finishes. Fantastic work!

You pretty much accurately described Q Switching. It has to be done with materials with long Upper Lasing lifetimes like Neodymium. Basically the active material can stay energized long enough. The Q stands for 'Quality' and it's also called Q Spoiling. That's an awesome looking Die. Thanks for showing us this cool build.

I love all your work! you are so amazing!

That color is incredible! I didn't even realize a rock like that existed. Excellent work as always!

It's definitely an interesting experience, seeing a crystal that's supposedly changing color between red and green, when you're red-green colorblind and cannot tell that any color change at all is happening.

Cherry lime dice, naturalistic blood magic!

I've been dying to see this ever since the rough went out! And somehow it came out even better than I hoped!

OH WAIT I DIDN'T PUT TWO AND TWO TOGETHER FROM HIS VIDEO. I found you a few months ago. I'm glad you're on this project collab.

I didn't know red and green could look so great mixed together.

I keep telling myself that one day i will be able to afford something as beautiful as this. One day.

I literally YELLED at the end 😮 you just continue to blow my mind to bits man.

That is simply gorgeous. I'll buy an advent calendar for the chance to win.

Turtle's Hoard has so many cool shiny rocks I wish I had the equipment and skills to make into cool shiny stuff 😭

It's always so awesome seeing a new video come out of your channel.

I don’t know how much I’d pay for this… More accurately, I don’t know how much I wouldn’t pay for this So beautiful I’ll have it… in my dreams… which will be good enough

This D20 is absolutely *gorgeous*.

Stunning work. The more I watch you work, the more I want to learn this skill.

Never ceases to amaze me... :)

I wish these dice weren't as expensive as they are but the amount of effort and craftmanship that goes into each one completely justifies the price. Sadly one will never be mine but I can at least live vicariously through these videos.

Cr:YAG is such a beautiful synthetic to work with, but I love the other dopped YAG and YAC synthetics as well! Nd:YAG is a gorgeous Pink-Lavender, while Ce:YAG is Construction Yellow and provides AMAZING facets and color bouncing. The difference for those in the comments between YAG and YAC is YAG is Yttrium Aluminum Garnet while YAC is Yttrium Aluminum Ceramic! (I am typing this up before I have watched the video, I'm just excited to see people working with YAG other than some Lapidaries that I know!)

Awesome editing with music, and stunning results. It looks amazing, almost unreal.

My brain doesnt work in the mathematical and geometrical way to understand how to cut facets lol. Always baffles me how you and jewelers do such precise and beautiful work

That end result is one of the most beautiful die I’ve ever seen I dropped an audible “omfg” when I saw it you truly produce one of a kind works of fine art never stop

. . . The fact you did a collaboration with Rybonator is wonderful.

This is THE dice. Absolutely amazing masterpiece.

So beautiful! ❤❤👍👍

Absolutely breathtaking. Loved the dramatic reveal at the end with the swelling music, it really made the final product so much more special.

ROLLLLL IT! I love these videos but I'm dying to see each of these get rolled across some velvet. Thanks for the great content!

Hearing you talk about some of the “secrets” for the craft is awesome! Keep it up with this amazing art you are producing and much love from Denmark 🙏

Keep doing what you are doing. Calm. Don't chase the RU-vid clicks. Love your vids as is.

It's still so cool to see how the star facets makes the dice so much more interesting. Keep up the great content!

i was sceptical at first as the stone didnt look great. but at the end I was amazed. this might be one of the best ones you have made

Damn that's so pretty! And the orchestral swell at the reveal... I'm having goosebumps and tearing up!

It certainly lives up to it's name!!! WOWWW

The dice you make are amazing! Also the crystal of this video is very pretty.

I can not think of a better gift to my dice gobbling husband. His favorite colors are green and red. This is wild! So awesome! This very nearly brought me to tears so beautiful

PLEASE keep these videos coming! I don't even play games with dice, but I'm fascinated with the process. Your video format is captivating!

You definitely have the master craft touch. Beautiful pieces. Also a joy to watch the care you take on every piece.

I want to see a laser built entirely from crystals faceted like this

So basically, the crystal is a mirrored wall until the light bouncing between it and the other side has enough energy to go straight through. Very cool choice of materials.

That reveal at the end was incredible! Beautiful! Absolutely beautiful!

Utterly astonishing and beautiful

I feel ya on those scratches. I'm grinding out a 12.5 inch telescope mirror (totally different than what you're making) and I got down to 15 micron grit and ended up getting some scratches from the tool. I tried to do a bit of surgery on the tool and ended up making it worse. So I've ordered some circular tiles rather than square ones and will make a completely new grinding tool to reduce the chances of scratches in the future. I'll have to go back and regrind it from maybe 220 grit onwards ending with 5 micron before going for pitch polishing.

What a beautiful die and PERFECT choice of music!!

That is devastatingly beautiful. It would look so fantastic in a ring. If it's durable enough to withstand the wear and tear.

Absolutely STUNNING.

Wow, now that is stunning!!!! Magical looking!

🌟 Forbidden Chapstick 🌟 such a pretty dice!

I am always so excited whenever you upload! I would give an arm and a leg for the chance to learn everything you know!

Truly exquisite. The numbers change a shade of color too

I'd definitely pay something to get a set of laser crystal dice. Cr:YAG, Nd:YAG, ruby, so many good options to pick from and they'd all be gorgeous

amazing results!

man that looks stunning! idk how you feel about suggestions, but I think you should totally check out cutting some lab grown opal! the rough is pretty cheap, and I'd imagine it'd produce an incredible die!

Absolutely stunning. As always. 💎🎲

The quality of your videos has only gone up since I've started watching, well done.

Absolutely beautiful!

Absolutely amazing

absolutely beautiful

This channel is so therapeutic

Your work is spectacular and these videos are all enchanting. Thank you so much for showing the process.

i really love this kind of channels, little amount of videos but really high quality, and really relaxing to watch

WHY THE FUCK AM I CRYING WATCHING THIS ARTWORK

That is absolutely gorgeous.

Fantastic! Another unmatched and fabulous piece of art. I am truly in awe of the skill you have to produce such masterpieces.

Perfect colors for christmas!

Awesome. Truly looks amazing.

Outstanding!!

Wow the glamor turn around looks incredible.

Aww, Rybo's video is private But I'm absolutely looking forward to seeing how yours turns out!

Absolutely phenomenal

I AM IN LOVE WITH THIS DIE SO MUCH OHMYGOSH I WISH I COULD HOLD IT IN THE PALM OF MY HAND! THESE TWO COLOURS COMBINED ARE MY ABSOLUTE FAVOURITE

In the B ROll at the end, if we didn't see like a small speck of dust, you could easily mistake the perfect polish and mirror like finish for a perfect 3D rendition of the die

Beautiful!

gorgeous!

The red and green compliments well in the light

It's so mesmerizing to watch how the piece of stone slowly formed into that perfect geometric structure. The way it reflects light is another level of amazement. And when you realise the amount of time and patience behind that fast forward timelapses and montage, it's really mind-blowing and deserves appreciation and respect. And then when you see the final result of all that time and labour, you realise that it was so worth it

Wow, another beautiful piece! Stay frosty!

Gorgeous! 😍

How beautiful! Wonderful video.

Just... Wow, amazing result.

It is simply amazing what you do here!!! I am just in Awe watching these videos.

You, your vision and creations are beyond value! Thank you for sharing…

Wow, this material is stupid beautiful!

So beautiful
