I bought a 5 watt blue laser while travelling in Bangkok. (at the MBK). It is powered by two cr123a batteries. The casing is some king of chrome covered steel and the whole unit is quite heavy (about 12 ounces) and 6 inches long.
When I focus the beam at objects 2 feet away they burn rather quickly. Of course, the darker ones burn faster.
I have very little experience with lasers but know enough to protect my eyesight.
My question is : Is there some way to check the actual power without taking the unit apart. What I mean is ; can I try burning a certain known material at a fixed distance that would sort of confirm that it is really a 5 watt laser with the correct ID and not just a 1 watt with a fake label. I know there are alot of cheap chinese made copies out there. I paid 2000 baht (64 usd) for the unit.
Thank you
