“…Pulsed laser sources with single frequency (SF) and diffraction limited operation near 1 μm are attractive in some applications such as LIDAR, gravitational wave detection and coherent beam combining, etc. [1][2][3]. For example, for the silicon photon trap detector commonly used in coherent Lidar, the laser response coefficient is much higher at a shorter near-infrared band.…”

We report on an all-fiber based high energy single frequency pulsed laser at 1030 nm with fixed repetition rate of 1 kHz. The system adopts a master oscillator power amplifier configuration. In the main amplification stage, we employed a highly doped, very large core diameter of 50 um YDF fiber as the laser gain media. 670 uJ, 500 ns pulse train was obtained, corresponding to a peak power of 1.34 kW. Such a high-peak-power and high-repetition-rate SF source is well suited for long range coherent imaging, optical remote sensing, and coherent interferometry, etc.
