Hi i decided to try making my laser IR because i wannted to see how it will burn
here is a pic of the crystal set and the laser
video coming later because im charging the batteries
it burns well
but cannot be collimated . I see fainth red dot on 25 cm after that it becomes huge 
its great because i can make it green verry verry easy . i just put the crystal set and i have a green beam
