Abstract

In order to maximize the communication speed of space lasers, and at the same time greatly simplify the space platform's laser capture/tracking/alignment/communication system, the use of fiber laser communication phased array technology is a new important way out. This study starts with the possible interaction between laser intensity coded communication and fiber laser phase control. On the one hand, the correlation between the structure layout of fiber laser phased array and laser communication system, the phased array phase lock, angle scanning and laser communication stability are studied. On the other hand, demonstrates that the modulation rate of laser communication may interfere with the phase locked stability of the phased array; 3 channels are selected as laser communication channels from a 8 channels 1064 nm fiber laser line array phased array system; Some valuable experimental data and preliminary results are obtained with cooperation of communication signal generation/detection equipment provided by the cooperation unit: For example, when in an 8 channels array, when 3 channels laser communication modulators have a communication speed of GHz, the influence to the main performance detection and evaluation methods of the fiber laser phased array. The above research provides an important design idea for exploring the feasibility of combining fiber laser phased array with space laser communication.
