I am building a ND:Yag DPSS laser using a 20w 808nm diode bar. I am kinda paranoid about vision safety, is there anything wrong with going with od7+ glasses that cover the 800-1100nm range. Are there any other wavelengths other than 808 and 1064 I need to protect against if I am not using a...

Ok, so i am doing my first build and most people will say that I am going overboard but my plan is to learn as I work through this as my goal is a DPSS for my cnc plasma cutter to turn it into a laser cutter/engraver. I am currently experimenting with a 20w 808nm laser diode bar which I...

I have a home build cnc plasma cutter and was interested in modifying it to do laser cutting/etching looked around and found that CO2 lasers are common but they require large space along with dangerous power supplies. Found a surplus source for 100w 808nm diode bars and thought maybe I would...
