Passively Q-Switched Single-Frequency Nd:Yvo4 Ring Laser With External Feedback
OPTICS EXPRESS（2018）
Abstract
A compact diode-pumped Nd:YVO4 ring laser was developed for generation of relatively long (few tens nanoseconds) single-frequency pulses for high-spectral-resolution LIDAR applications. Exploiting the feedback from an external mirror and Cr:YAG passive Q-switching with pulsed pump, unidirectional single-frequency operation with high quality similar to 50-ns, 80-mu J TEM00 pulses was achieved from 100 Hz to 10 kHz. Amplitude, duration and repetition rate stability of the pulses was better than 1%. (C) 2018 Optical Society of America under the terms of the OSA Open Access Publishing Agreement
