Abstract

The experiment found that 10.6 micrometers wavelength laser incident on a bulk germanium affects conductivity of germanium. The change of conductivity is ascribed to a ultrasonic field excited by change of laser power, which scatters carriers in semiconductor and results in a change of conductivity. Relative change of conductivity (Delta) (sigma) /(sigma) approximately equals 5 X 10^-4 is observed when laser power changes about 1 Watt. Application in mid-infrared laser detection is proposed and discussed.
