Abstract: A laser system is provided that includes a modulated laser, which is configured to generate an amplitude modulated laser signal, comprising a first amplitude modulation. The first amplitude modulation is based on a data signal. Moreover, the laser system includes an optical modulator, which is configured to receive the amplitude modulated laser signal as an input signal, and modulate the amplitude modulated laser signal with a second amplitude modulation, based on the data signal, resulting in an amplitude modulated output laser signal.
