keeping a pointer cool

[maxkillz]

If I found a way to keep my green laser pointer nice and cool would it be possible to run it for as long as the batteries will last? could I just go outside in the freezing cold and wind and keep it on as the barrel of the laser probably won't exceed 60F? I just want to test how long certain types of batteries last under constant stress. I am testing a >130mW alpha from NOVAlasers the power doesn't decline until both batteries are putting out under 1.1V under no stress so I think it only need about 2V to run

I'm still a noob but even i can guess that it should be possible, how else can manufacturers estimate the batter life of certain things other than a shot in the dark

Keeping the batteries cool will make them last longer, but wont that effect the laser its self as they don't like cold? I refridgerate my cell phone batteries. lol

nothing will get over 60F in this weather and the wind should help dissipate the heat that is generated

Your idea of operating them in cold weather won't work. Green lasers have an optimal operating temperature range.

Yea , and in cold weather it will stabilize just nicely, if not you can help warming it a bit in your hand. I used to leave my diy red on for 10-20 minutes at a time on a tripod in the cold.This might not work as well with a DPSS but if you keep it in your hand it should be ok. :-/

hmm, so if I can stabilize the temp using my hands to warm it up a bit could I run it for long periods of time?

Hands get cold quick. This is only a guess. Proper operating temps runs from about 70 - 85 degrees. You could call the company and ask them what the optimal operating temps are.
