This paper presents a scheme of pulse compression lidar with enhanced electrical modulated bandwidth. An ultra-wideband linear frequency modulated signal with a bandwidth of 50GHz is generated using femtosecond laser and superimposed linear chirp fiber Bragg gratings in the transmitter, which separates the echo of the target from the backward scattered noise with low modulated frequency. An optical...
A robust, cost-effective external-modulated ultra-short pulse generator based on chirp compression and Mamyshev reshaper is simulated numerically and demonstrated experimentally. We investigated the quality of the pulse with numerical calculation, demonstrating that the pulsewidth and pulse pedestal can be significantly improved after optimization. The role of out-of-band suppression ratio of the...
