Abstract: This paper uses the method of pulse MOPA fiber laser with the PPM modulation to achieve. This paper first describes the characteristics of space laser communication requirements and technical issues that need to be addressed, And then, according to the requirement analysis the MOPA transmitter program, and prove its accord the high power and the high rate what the space optical communication requirements. Through the analysis for PPM modulation mode, the MOPA type fiber laser based on the PPM modulation system is designed. Through the simulation verify its can reach 1 Mbps transmission rate and 5W average power.

 

Keywords: Laser communications, PPM, Fiber laser, Modulation, MOPA.
