3D chaos lidar system with a pulsed master oscillator power amplifier scheme.

We investigated the characteristics of chaos-modulated pulses amplified by a pulsed master oscillator power amplifier (MOPA) for application in a new chaos lidar system in this study. Compared with the loss modulation applied in a continuous-wave (CW) time-gating scheme, the pulsed MOPA scheme could generate chaos-modulated pulses with much higher peak power, resulting in an improved peak-to-standard deviation of sidelobe level (PSL) in correlation-based lidar detection. When the pulsed MOPA scheme was applied at a duty cycle of 0.
