摘要
A high-repetition-rate single-frequency injection-seeded Q-switched Er:YAG laser with a 'double reflection' architecture is reported. Single-frequency laser pulses at a pulse repetition frequency (PRF) of 2 kHz are obtained by using 'ramp-fire' injection-seeding technique. The half-width of the pulse spectrum is measured to be 2.05 MHz by using the heterodyne beating technique. The novel 'double-reflection' architecture is employed in order to achieve a stable high-repetition-rate single-frequency operation. As far as we know, 2 kHz is the highest PRF achieved from a single-frequency, injection-seeded Q-switched Er:YAG laser that can be used in a wind Lidar system.
