Abstract :
The fractional thermal loading, the ratio of heat generated to absorbed energy, at a 6.5 at.% doped Yb:YAG crystal diode pumped at 0.943 μm has been measured to be <0.11 under conditions of no laser extraction. This quantity ranged from 0.37-0.43 in 1.04 at.% doped Nd:YAG pumped at 0.808 μm. Under conditions of laser extraction, the fractional thermal loading in Yb:YAG is expected to remain nearly constant, whereas that in Nd:YAG at 1.064 μm can be expected to drop to ~0.32
