Improvement of a Ge:Cu photoconductive detector in time constant has been attained. Q-switching CO2 gas laser pulse was used for the determination of the time constant. The time constant of 20 ns has been obtained at the breakdown region. Noise equivalent power (NEP) of 5.3×10-10 W/Hz1/2 at the chopping frequency of 500 Hz has been obtained at 20μm in wavelength. This photoconductor is suitable for the measurement of high frequency phenomena in the infrared region.
