I tried this with red laser...the sine wave stay is my eyes to five week... i use speaker to move mirror Y and laser rotation motor X of left right (wire less power inductive coil). Like much your gcode ideia. Tanks for share!
@@WoodenWeaponry ty but it is funny how we are still seeing the intense lines of both volumes as if there is lasing and stimulated emission still happening although no output , there really should not be such sharp line if the resonator is not aligned and should only appear once mirrors align
Ah, I see what you mean. The fluorescence comes from the pumplight entering the crystal (first stripe) and being reflected and focussed back into the crystal by the curved OC mirror (second stripe).
they said a ruby can not operate in cw mode as it has something to do with the energy level of the chromium atoms and their short excited state time etc ,,i need to stop listening to ppl and understand these things myself to know if it is possible or not because i too ever since i been fascinated with lasers always wondered if it's possible to run a ruby cw
Hi, very good the home project. Would you please tell me the distance of the back mirror and the front mirror with the laser rod, or how to calculate the distance. Thanks. William.
hmm is the wavelength different than the typical 694nm you get using a flash lamp because you are using another pump source and its absorbing and emitting something different frequency?
in your schematic at 9:50 why does it show the output beam diverging after the oc? is this what actually happens if so do you not need a lens to collimate it?
nice but would have been nicer if you had it running through smoke in the dark with the cam facing the output side to really see what the beam looks like
one reason why the retail blue diode engraving laser systems have retangular spot shapes is that they are not truly "beam combined". in these systems, the term used is "Knife edging" and its *not* the same approach as the coherent or spectral beam combination that is used in the "serious" technial laser designs in commecrial systems (commonly used in Fiber-Pump modules, eg see the IPG photonics website, where they have images of de lidded modules showing their internal optical setups) essentially the rectangular beam is created when multiple beams *DO NOT* follow the same perfectly co-axial path/alignment, and actually allign *slightly* off-center, spaced laterally relative to each other (in addition to a "dumb" aperture that may be filtering as well) to the naked eye, these arrangements can appear to be similar or identical. a few of the stage laser ompanies have diagrams explaining the whole "smeared out" imperfect overlap "Knife edging" approach
great explanation and demo of the DPSS. Can you explain more how you made the optics and would it be possible to simply get a ruby rod and cut it to size then surface grind the edges flat?
6:40 - Wow, that makes sense. Thanks for this great explanation. What type of focusing lens did you get? Do you need to calculate which anamorphic prisms and focusing lens needed before buying? If so what are the calculations?
