High power long-wave infrared laser based on polarization beam coupling technique [Early Posting]
We demonstrated a high power long-wave infrared laser based on a polarization beam coupling technique. An average output power at 8.3 μm of 7.0 W was achieved at maximum available pump power of 107.6 W, corresponding with 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 8.3 μm was obtained at the maximum output power.
