Optical amplification and pulse shaping of ultrashort gain switched pulses by a diode laser amplifier

摘要

Examines the amplification of long wavelength picosecond gain switched optical pulses using a semiconductor laser amplifier. The effects of gain saturation on the picosecond optical pulses are examined with the diode amplifier biased by a constant current, and a new form of enhanced pulse shaping and shortening is demonstrated. An investigation of the properties of the amplifier when strongly modulated by a microwave electrical signal is reported. Here, pulse amplification and temporal pulse gating is demonstrated.
