What color is it? YAG lasers produce the 1064 line which is invisible, 532nm is green and 473nm is blue. Your laser seems to have all 3 according to the sticker but which is it?
I can make out PGL in the model numbr section that usually means "portable green laser". Is it green?
The next question would be... is it working? what is it outputting? Is it stable? What mode does it run in?
We need more info.
