For the more mature and widely used trend of the space laser communication,in this paper,the techniques study of space laser communication countermeasure is presented. Firstly, the interference characteristics of photoelectric detector used for the optical communication is analyzed and simulated from two ways with bits and clock extraction interference by using Matlab. Experiment system is constructed in the laboratory. The test results show that the inter-ference effect of photoelectric detectors is related with the parameters such as frequency and power of interference sources.
