Laser Pointer Forums - Discuss Laser Pointers | High Power Lasers

I have recently started working in the field of biophysics and so I came across stuff about LASERs and LEDs that I needed to understand. I have made little progress... ALso this is the first time I've registered on a forum, and I'm also learning how things work around here. It's a fun (and informative) place from what I can tell so far.. plus I never could have imagined so MANY people had LASERs as a hobby!!!! That's like a really big surprise for me

I hope I'll someday reach the stage where I can not only ask but also answer questions on LPF

Edit: I'm from India!
