Abstract :
A diode-pumped room-temperature Ho:Tm:LuLiF4 laser achieved an optical efficiency of 9.4% under normal mode operation. Under similar experimental conditions. Ho:Tm:LuLiF4 yielded 1.5 times greater optical efficiency than Ho:Tm:YLiF4. Absorption spectra and lifetimes as a function of pump energy were measured for evaluation of this laser material
