Abstract
A method includes applying a boost pump signal to a pump laser of a laser system based on a preceding off duration associated with the laser system, and applying a forward pump signal to the pump laser. A laser system includes a seed laser situated to generate seed optical pulses, a pump laser situated to generate pump optical radiation, a fiber amplifier situated to receive the pump optical radiation and the seed optical pulses, and a controller situated to select a pump boost duration or pump boost magnitude based on an off duration associated with the laser system.
