Hey laser enthusiasts. I've been introduced to the wonderful world of lasers by Styropyro. I must say, I have no idea what safety precautions to take, what there are, laser types, how wavelength affects features of the lasers etc. I've had a couple of handheld (~5mW) green pointers in my life (I'm 16 years old) and i want to attempt to make a laser and in general get into the hobby. I don't plan on working with >5mW lasers so i dont think i have to purchase safety glasses, although as time passes i'll have to. That being said, can someone tell me what i need in the very beginning to build a very crude (working) laser and build my way up? Parts, machines and schematics are welcome.Thanks in advance for all your replies and I hope I'm welcome!
