Powerful homemade diode pumped Pr:Ylf laser!

In this video, I show you a laser setup using a Pr:Ylf crystal. This crystal can emit at multiple visible wavelengths (green, orange, red and more) which is quite rare for laser gain media.
► This setup also reaches quite high output powers (above 300mW) and shows some beautiful TEM modes!
► If you want to know more about this laser, I've written an article on my website about it: www.sci-projects.org/blog/diode-pumped-prylf-laser-emitting-at-640-604-and-523nm
► This project also has a GitHub-Page for more details: github.com/NiklasHammerstone/PrYlf-Laser

How to align pulsed lasers with plane mirrors

Переглядів 1,3 тис.2 роки тому

Laser resonators with plane mirrors (typical for Nd:Yag or ruby lasers) are notoriously hard to align without special equipment. In this video, I show how it can be done quite precisely in a home workshop like mine. All you need is a second collimated laser (like a HeNe) and an adjustable mirror. This method works quite reliably and without much prior experience in this field. Great videos abou...

► My blog post about this laser: www.sci-projects.org/blog/cw-diode-pumped-ruby-laser ► Thanks so much to Dr. Walter Luhs for his help in this project! This is the paper I based this design upon: dx.doi.org/10.1364/OSAC.2.000184 In this video, I show you, how I made a continous wave diode pumped ruby laser. This is quite an unusual build, since the vast majority of ruby lasers are pulsed. Altho...

► In this video, I show you how I built a laser engraver which works by rotating mirror and therefore deflecting the beam in a controlled way. ► This whole machine is built from scratch using a Teensy 4.0, TMC2209 stepper drivers, stepper motors, optical components and more. ► Prototype video: ua-cam.com/video/GXrqjjgx8w8/v-deo.html ► Laser optics video: ua-cam.com/video/lOmr7BwdiJU/v-deo.html ...

GITHUB FOLDER BELOW ► In this video I show you the laser scanner I've been working on for the past few weeks. This machine turns mirrors very rapidly to create an image on plane. This is called "scanning" ► Normally this is done with high speed galvoactuators, but I wanted to try to do it with stepper motors ► GitHub Folder github.com/NiklasHammerstone/GalvoStep ►If you liked this video please ...

► In this last episode we are going to make the ventilation and filtering system for the smoke the cutter produces ► If you want to make a Laser cutter, I'd strongly recommend making or buying such a system. ► I didn't specify any flow data or anything, because your system is very likely different, so it wouldn't be of much use. ►If you liked this video please give it a thumbs up :) If not, giv...

► It's time for the laser tube to be installed! ► The Laser can now be focussed and fired. But this is of little use without a proper air filtration system, so this is what I will be building next. ► For all of you who think that this is not necessary, just light a bonfire in your room and keep it going for a few minutes to get a reasonable comparison. ►If you liked this video please give it a ...
