Abstract
An optical amplifier system comprises an optical gain medium receiving an input optical signal and outputting an amplified optical signal and a pump laser optically coupled to an input of the optical gain medium, wherein the pump laser emits a series of pulses to the optical gain medium, the pulses being emitted during coherence collapse operation of the pump laser, the time between pulses being shorter than an excited state lifetime of the optical gain medium.
