Guys, current green lasers work in temperature range between 10-30C only.
This is because of their design (on wikipedia you can find why it is like that, and it was discussed in another thread last month, I think).
We will have to wait for new lasing materials to be developed before we will be able to use them in wider temperature range .. and for affordable price of course:-). The story is similar to the development of LED's - first there were red LEDs, then amber.. and only couple of years back we have commercialy available Blue (and White, which is actually blue LED radiating into fluorescent medium which absorbs and re-radiates energy in green-red bandwidth, which then appears white to our eyes).
