Laser Projectors as Fast As Possible 

Laser RGB!!!!

Laser Sex Dolls? See son? That's the future right there!

Hey here's a comment that's actually relevant to the video! Laser projectors are amazing. They're slowly being rolled out at the university I work for and they require virtually no maintenance, the image is bright and they also effectively remove the potential for timing errors between them and the control equipment that the end user will operate. Not to mention of course the instant on and off is super helpful when you're trying to troubleshoot a professors laptop connection in the middle of their class.

Damnit John! You had one job!

Fookin laser sights

2:05 As a german what was that ???? xD

So here's a question. Say I am pointing my laser beamer at a white wall and I have it turned on for about 3 - 4 hours every night. Will the laser have any long term effect on the paint of my wall? Will I notice more wear when compared to a normal beamer? How long will it take for the laser beamer to have a visible effect on the paint on my walls? This problem would probably be avoided by using on of those projector screens, would I need a special screen for a laser projector however? So maybe more than 1 question but still, if anyone knows the answer I'd love to know.

You've seen all the warning that come with laser pens about looking into the beam. This makes me wonder, do laser projectors have the same dangers. If your laser projector is set up in your living room and your kid catches a faceful of HD glory as he walks between it and the wall, are his eyes going to literally get burnt out of his sockets?

2:05 what the Fuck happened here?

This was incredibly interesting. Thank you

Thanks a lot for making this video! Answering a lot of questions i ve had when i asked you to make a video about this stuff. Cheers and greedings from Germany :)

You forgot to mention that laser projectors are closed systems so the cooling doesn't suck in the same amount of dust and particles, prolonging the lifetime. However, this means that changing it will be much more expensive than the separate conventional bulbs we have today, should you need to do so. They also emit less heat and can be used in any angle. Regular projectors need to be told what direction they're hung and often switch to a portrait bulb in case you want to use them on the side. The high end units we use in the rental business start somewhere around $20.000,- with a default lens kit. Then you want to add more lenses, brackets, flights and infrastructure. 😎

simplified but concise description, good job!

Cinerama in Seattle has a laser projector, and it's freakin' awesome!

I like how your thumbnail gives a good idea about how it works. Thanks!

Wow ... It helped me a lot.... Cleared my confusions.... Thank u Sir....

Previous company I worked for produced laser projectors, some almost the size of a small car (without about the same cost). The company I NOW work for buys these projectors and uses them for Air Force training domes.

Those kinds of different used technology types of projectors are amezing.

you guys should do a quickie on contrast ratio in projectors.

30000 hours is 10x longer than the bulbs at the cinema I work at.

But arent lasers dangerous if pointed at the human eyes? Can you explain that misconception

I do see this becoming more consumer pretty soon, I have had chance to play with the Epson projectors (perks of working there) and the contrast ratio is fantastic, also yes the laser life is pretty accurate.

Sorry Linus. Austin Powers was 20 years ago, not 15 :D

That "gtfo" run at the end made me chuckle.

That joke in the end was hilarious!

must say i love the sarcasm on this channel!

Really Enjoyed the John Part !

Here we are in 2022, now, and these things can be had for as little as $300, and they can be battery powered and portable, with bluetooth and wireless built in. Wow, what a time to be alive!

Great video as always

"LASER SEX DOLL" - I just lost it and rolled on the floor xD

You have a better control on your colors with three seperate monochromatic light sources (unique wave lenght). lasers are also coherent sources (a simple wave, so not multiple phases at the same time), we can create inteference with two beam that come only from the same laser (it can't work with two laser, even if they produce the same wave lenght: waves are not perfect). So for laser projectors, no intefrence are created. A fun fact with interference and laser, we can do holography : recording the 3D perspective of an object by recording with a photographic plate the interference between two beam (one reflect on the object and the other come directly from the source) with one laser, and reconstruct the object with only one beam.

This video was both informative and... extremely funny!! One.. und wunly one!! That was epic!

Nice Episode :) I would have liked to see a bit more info on how the image is created on a pixel level...and what about this German joke? :D

I am still dying from the ending

Corporate was suggesting NEC 8k laser projectors for us this year. The way they were set up was basically a single chip DLP projector with a color wheel. They were still ridiculously expensive, we could have bought two halogen lamp projectors for the price of one.

Video is out of focus. Someone fucked up.

Oh.... MicroVision is going to get so much attention on Monday. So glad I am already invested :p

Already have one. It is freaking awesome.

good Information here thanks

Now I need a rgb laser projector to put in my home. already installed my remote controlled rgb lighting thanks Linus

We got one in one of the classrooms at my work. My understanding is that it cost $20k. 30,000hrs of operating time may sound like a lot, but our instructors often don't turn the projector off when they're done, so we'll see how it goes.

i lost it with Jon running away xD

Why not put the link of additional video about the colors, into the description of this one? Thanks for the quickie

John knows how it is

Thatcher smiles evilly

Love how he was trying to let out the German here and ended up only using a single German word in that part, "und".

Does that mean looking at a laser projector directly (perhaps by accident from passing in front in a classroom) give a greater chance of causing eye harm?

I use a pair of Panasonic RZ770 7k laser projector at work. They are so much better than the lamp-based counterparts (DZ770). I absolutely love them. They use the same interchangeable lenses as all the Panasonic 1-chip projectors use. If you work in AV you should definitely check them out if you haven't already!

The majority of laser projectors (not just in the consumer space) are laser phosphor. It's not cheating. Whether RGB laser or laser phosphor, the the primary colors are combined to make write before getting to the light engine, where they are then separated by a prism the same as in a lamp projector.

One note linus: Make it laser video projectors. I use laser projectors too but these do vectors and not video!

Can you do a video on file format conversions (like with avidemux) and how they achieve that?

2:03-2:06 if you think I'm not going to snip that part and use it in a video on my channel you are quite mistaken sir.

2:05 worst German impression ever!

You can make another episode on LTT, to investigate whether projector screen is better than white wall.

Love the gold shirt Linus

I wonder, could this guy speak if his wildly moving hands were tied behind his back?

I did a quick search and found that most laser projectors employ one laser light source and the operation is the same as LCD and DLP projectors. The laser is only better because it is potentially brighter and more efficient light source, similar to the success of LED over lamps

Imagine looking into the projector by accident *_OUCH_*

I want to know if only laser is enough to create the picture or DLP chip is needed?

You can't separate blue light into red and green light, what's happening with the phosphorous (I assume) is that the light is being absorbed and new light is being emitted at different wavelengths.

His German reference reminded me of the first Be quiet! power supply unboxing he did. Man that was a long time ago.

Just wondering how about safety? There was review of some pocket size laser projector with laser class 3R.

Please let John know he doesn't need to slam his feet on the ground while he runs. Just looking at him hurt my knees.

this was done like 7 years ago by Mitsubishi. the projector failed for the consumer market. but man that image was amazing

The best mini projector that you can find in the market for this price range!

I'm on time, almost precisely on time. Laser precisely on time...

Do laser projectors also produce the rainbow effect DLP projectors show when you move your eyes?

Superior laser race represent

The other benefit to laser projection is that the contrast is much better!

I got lasers in my eyes.

that only one joke is killing me rn

why is the sound so low? I just watched the video about Float Plane from Luke and the difference is noticeable.

@2:05 i was about to fall of my chair because i laughed so much :D

I love IMAX with laser.

We use laser projectors at work and we love them.

Yeah I got all this from that "not all projectors are created equal" RU-vid ad.

Guys i love the new scripts keep the jokes flowing

You're forgetting to mention that usually laser phosphor technology uses a color wheel to produce other colors.

Laser Sex Doll sounds like a fantastic band name.

Austin Powers came out in 1997. 20 years ago, Linus. We be oldin'.

That last joke wast hilarious! Hire that guy back!

What about Casio XJ-A252? It is a Laser/led hybrid and I got one in my house (for cheap from an eBay valet seller). Edit: Found out red is produced by LED, blue by laser, and green by blue laser from a phosphor. Still pretty quiet compared to lamp-based projector.

4:16, john stole my burgers......

One of the best features wasn't even mentioned: true blacks. Just like OLEDs in comparision to regular LCDs, the black pixels are actually "off" (or in this case not lit by the lasers), and not just backlit dark pixels, which leads to insane contrasts. If you haven't experienced it yet (and want to ruin every regular cinema forever for yourself) go see some movie in an IMAX Laser 4K theatre. It's like going to the movies for the first time in your life :D

Is the weapon of the futur a laser that kills you while displaying a pony?

Why can't I just get some frickin' lasers with sharks attached to their heads?

Trust me, $8,000 is a good deal for a TUE 4K projector! It means the price will go down even further! can't wait to grab one!

When Linus said the Laser Sex Doll, I suddenly got more interested in that

Do you think that cinemas will adapt this technology soon?

first Luke now Jon... I'm guessing LMG is hiring new emplyoees again soon :D

so a bulb based projector is like an LCD screen and a laser projector is like AMOLED

Laser eye surgery + laser things NASA uses + Laser wireless technology + IMAX Laser are the best. Other things like laser mouse are usually not good enough.

"Work hard, quit hard" - John, 2017

We had RGB since ages, this new RGB will be usless

Lol I did research on laser RGB Displays for my Engineering Optoelectronics course. I know all about this :P

Let's not forget the Pico projectors that can fit in your pocket. I imagine what laser technology can do for them: bigger battery life, better brightness, smaller size... What about other applications for this technology: Less heat, more light, better image... I bet we will be seeing very creative uses for this technology.
