Several pulse response property of Avalanche photodiode (APD) were discussed in the paper, including the amplitude nonlinearity of large optical power signal input due to space-charge-effects, the reshape property and time domain property from the nonlinearity model of APD. In the pulse response measurement experiment, the APD was illuminated with a pulsed laser diode whose impulse width is several decades nanosecond with peak power up to decade watt. The experiment results showed the nonlinearity pulse response was well matched with the model numerical simulate result. The affect to the APD based range finder and Ladar was discussed and useful correction solution from the model was made especially for pulse TOF range finder.
