Saturation behavior of p-type germanium at CO(2) laser wavelengths.
Observed bleaching of single-crystal p-type germanium in the 10-microm region obeys an inhomogeneous broadening model for input intensities up to 100 times the saturation intensity I(s). Bleaching measurements show that I(s) varies from about 3.2 MW cm(-2) at 10.59 microm to about 6.8 MW cm(-2) at 9.27 microm. No significant variation of I(s) with crystal orientation is seen. Applications to CO(2) laser system isolation are discussed.
