laser temperature vs power

[zxn474l]

What would the temperature of a 2 watt 808nm laser at a close focal point be in degrees farenhight? Is there some kind of formula for this? What about a 400mw 405nm laser at the same focal point?

Get some lasers and some thermometers... and let us know...

It all depends on how much of the laser's power is absorbed and
how much of it is reflected...

I personally don't know of a formula..... too many variables...

you can find the temp of the lasers point by building the IR thermomiter power meter described here!!!! just focus the point on the black foil and hit the button to get the temp!!!
