Efficient Long Wave IR Laser from Ho：YAG 2 μm Pumped ZnGeP2 Optical Parametric Oscillator

An efficient high power long wave infrared laser based on ZnGeP2 optical parametric oscillator pumped by a 2.09μm Tm：YLF/Ho：YAG laser at 10KHz pulse repetition rate is reported. The pump to idler conversion efficiency is 8% at 15.6W Ho pump power level and a quantum efficiency of 31% when the 1idler...

Summary:An efficient high power long wave infrared laser based on ZnGeP2 optical parametric oscillator pumped by a 2.09μm Tm：YLF/Ho：YAG laser at 10KHz pulse repetition rate is reported. The pump to idler conversion efficiency is 8% at 15.6W Ho pump power level and a quantum efficiency of 31% when the 1idler wavelength is tuned at 8.08μm. The wavelength tuning range from 8-9.1μm is also achieved by rotating the ZGP crystal.
