摘      要：We demonstrated a high-power long-wave infrared laser based on a polarization beam coupling *** average output power at 8.3µm of 7.0 W was achieved at a maximum available pump power of 107.6 W,corresponding to an optical-to-optical conversion of 6.5%.The coupling efficiency of the polarization coupling system was calculated to be approximately 97.2%.With idler single resonance operation,a good beam quality factor of^1.8 combined with an output wavelength of 8.3µm was obtained at the maximum output power.
