Abstract
An optical system is provided having a laser configured to generate light having a first laser spectrum with a first linewidth, a waveform generator configured to produce a noise waveform, and an electro-optic phase modulator in optical communication with the laser and in electrical communication with the waveform generator. The electro-optic phase modulator is configured to receive the light having the first laser spectrum, to receive the noise waveform, and to respond to the noise waveform by modulating the light to produce light having a second laser spectrum with a second linewidth broader than the first linewidth.
