Laser transmitter for generating a coherent laser output signal with reduced self-phase modulation and method

摘要

A laser transmitter is provided that includes a seed signal generator, an amplitude modulator and a power amplifier. The seed signal generator is configured to generate a seed signal that has a continuous waveform. The amplitude modulator is configured to generate a flat-top pulse signal based on the seed signal. The power amplifier is configured to generate a laser output signal based on the flat-top pulse signal.
