Laser Pointer Forums - Discuss Laser Pointers | High Power Lasers

Hi, I'm a student from Taiwan. My first build high power laser was M140 1.6W blue laser, now I have 1 M140 diode and 2 high power red laser diodes, I also want to build solid-state laser and CO2 laser, but it too expensive, and this year, I want to build a laser per month.
