A high power, variable repetition rate, picosecond, optical parametric oscillator pumped by an amplified gain-switched diode

Abstract

We demonstrate a picosecond optical parametric oscillator synchronously pumped by a gain-switched laser diode, which is amplified in an Yb-doped fibre amplifier chain. Up to 7.3W at 1.54µm and 3.1W at 3.40µm is obtained at pulse repetition rates between 114.8 and 918.4MHz
