Using ATP technology to build airborne laser data link，it can realize laser burst communication between aircrafts.The paper mainly analyzes the laser burst communication system,ATP technology and makes simulation with Optisystem software.To ensure data correctness and completeness in high-speed burst data transmission，the system adopts special frame structure and data encoding method.Simulation results show that the burst communication system can meet the need of the communication requirement and the minimum error rate is 10-10.
