This is the laser with cooling liquid. If the laser will warm up too much it will change color. Laser heats up when it hits the material is indestructible (DMND, INSL, COAL) Overheating will cause damage the laser
SING destroy and overheated the laser (put it on the ray of laser)
But, what's the point of cooling in this laser? First, you heat the photons, and then, you want to cool them down? And why you've put the GPMB? When i start the laser it breaks: http://img716.imageshack.us/img716/9891/zzzsvp.jpg
