【Abstract】 By using the apparatus given in this paper the experiment on photo-conductive switches was conducted to investigate the affection of both the laser energy and bias voltage on switch output. By means of the same set-up, the carrier lifetime of Cr: GaAs used was measured to be as 1.8ns, and the possibility of the set-up to be utilized as a high speed photodetector has been demonstrated.更多还原
