woop said:would a tec thermopile be useful for measuring laser power?
maybe if i put it on a heatsink and paint one side matte black.
I know it would be uncalibrated but would it work and be consistant
I see you had the same idea as me... I started a thread on it and tried it yesturday.
I wasn't happy with the results, which is why i'm here now...
A peltier is very sensitive, and creates a voltage, relative to the power of the laser.. It would have to be multiplied of course, but unfortunatelly, it is VERY slow...
It takes a while, till it climbs to the highest voltage a laser can produce, and the higher it goes, the slower it becomes.. Also, it wouldn't absorb all wavelengths the same, so it would be similiar to a solar cell, only slower....
