Hey all! On my quest to better understand the fundamentals of lasers I stumbled upon this very interesting video published by the Massachusetts institute of technology. It goes through the basics of the physics behind lasers and oscillators and their properties, Enjoy! Laser Fundamentals I |...

Why is everyone posting about cutting using 808nm to cut?...I understand that the initial discussion was about that but, as I posted above, I turned away from the idea, since you guys convinced me that the laser was of bad quality and could not be used to "Cut" cleanly. My intend is to use a...

Hi MarioMaster, As I mentioned, after discussion, I dont intend to cut with a 808nm diode. I will be using a 1064nm wavelength emitted by a Nd:YAG rod that will be pumped by the 808nm diod array. So this video is not representative of a cut made by a Nd:YAG laser. here is a video that i closer...

Again, Thanks for the feedback! I'll definitely have a look at "the book" . Nice video! I realized that, being a student at university, I had access to TONS of experiment reports on lasers and I found a couple of interesting ones I though you might want to have a look at... ( I don't know if...

Thanks for the detailed feedback! you guys are awesome. lol meatball: And sorry for not googl-ing it you're right it would of been a simple search. Alright so If I conclude well, I'm better off to build a laser from a Nd:YAG rod because, although I will loose efficiency, the outputted laser...

Hey everyone! I'm pretty new to the world of lasers but i've been doing quite alot of research. I'd like to build a solid state laser based on 808nm laser diodes that would cut metal, say 1/4" thick, that would ultimately attach to a ShapeOko CNC. Here is list of quesiton i'd like ansered I...

Hello everyone, I'm completely new to the world of lasers. I'd like to built a laser cuter to cut thin pieces of metal and wood. I Have a few questions that have been bugging me about laser and power ratings etc. First off, I see a lot of 5 Watts 808nm laser diodes on eBay for 120 US dollars or...
