Abstract
Observed bleaching of single-crystal p-type germanium in the 10-μm region obeys an inhomogeneous broadening model for input intensities up to 100 times the saturation intensity Is. Bleaching measurements show that Is varies from about 3.2 MW cm−2 at 10.59 μm to about 6.8 MW cm−2 at 9.27 μm. No significant variation of Is with crystal orientation is seen. Applications to CO2 laser system isolation are discussed.Keywords
