Use of a LiNbO{sub}3 Modulator Gate in Amplification of Femtosecond Optical Pulses Generated by a Passively-Mode-Locked Erbium-Doped Fiber Laser

摘要

127-fs, 4-kW pulses by a mode-locked fiber laser were gated to reduce the repetition by a modulator and amplified by an EDFA. The net gain of 50 was 11 times that without a modulator.
