Laser as heat source for quartz

Lasers are only able to heat an object if that object can absorb the light it puts out. If the light is transmitted through or reflected off the object it doesn't cause the molecules to vibrate enough to cause heat. It is the energy of the laser light that is transformed into heat by its absorption. Apr 1, 2020. #6.
