Guy Does a Laser Experiment at Home With Dry Ice

This guy does a cool test at home studying the cooling properties of dry ice on his homemade laser. Here is an excerpt from the experimenter:

In this video, one of my laser diodes is tested to destruction with an interesting cooling experiment. The experiment was to verify whether or not a larger power output was possible from a “medium” power diode(ML101U29-25) under almost cryogenic temperatures. The diode suffered from a “thermal runaway” in the end, as was determined by the self-increasing current effect. This diode definitely seemed to be outputting over 1W of power, but I cannot say for sure.(I need a laser power meter)

This is really cool. Btw do not try this at home or without the supervision of a professional!

Let’s see what happened with his laser in the video on page 2
