Simulation Study on Self-Focusing Effect of Satellite Laser Communication Under Extreme Ionospheric Conditions

Satellite laser communication has developed rapidly, with advantages such as strong anti-interference ability, good confidentiality, high communication rate, freedom from frequency resource constraints, large capacity, small equipment size, low power consumption, and light weight, which can meet the increasingly high requirements for data transmission rate and security in maritime communication. When laser propagates in the ionospheric plasma, the laser pulse undergoes a self-focusing effect. Under extreme conditions such as sudden ionospheric disturbances, the electron density in the ionosphere greatly increases, which has a significant impact on laser transmission. This article analyzes the mechanism of focused beam generation, uses PIC method to simulate the self-focusing effect of laser under extreme conditions in the ionosphere, and studies and determines the method of introducing self-focusing effect in PIC simulation. The self-focusing electric field structure is compared with beams without self-focusing with the same parameters. The results indicate that when laser propagates under extreme conditions in the ionosphere, the front edge of the laser pulse bends, and its laser oscillation frequency increases. In the latter half of the laser pulse, due to the self-focusing effect of the plasma, the width of the laser pulse decreases and the focusing effect is obvious.
