Question about lasers and cold?

[goa2000]

my laser is rated at 100mw and a working temperature 20 to 30 Celsius what would happen if i was to use it at low temperatures and even sub-zero temperatures.... ie. -10 to 10 celsius?

A lot depends on the laser. Some green lasers will mode hop if they are too cold and some 445's run more powerful.
