Paper Abstract

In this paper we describe a compact optoelectronic circuit for spike-free nanosecond pulse generation in semiconductor lasers. The device is designed to work as an injection seeder in high-power fiber lasers built in master oscillator power amplifier architecture. To reduce a significant pulse distortion resulted from relaxation oscillations, a technique called light injection was used. It allows achieving the pulse generation with excellent temporal and spectral properties. Smooth pulses with duration of 1.9ns and narrowband spectrum with a central wavelength of 1550nm have been presented experimentally.
