Abstract: Seed pulse generators for fiber amplifier systems include a seed pump controller coupled to a seed pump laser diode. A photodetector is situated to detect seed pulse generation, and is coupled to the seed pump controller so that seed pumping is decreased upon pulse detection. For a laser diode pump source, a pump current can be pulsed to produce a seed pulse and then decreased to a bias level such as a DC bias current that is less than a pump laser threshold current. Single seed pulses can be generated with reduced pulse jitter.
