Abstract

A single-frequency diode-pumped Q-switched Er, Yb:phosphate glass laser that oscillates at an eye-safe 1.54ηm wavelength has been developed for use in coherent Doppler lidar. A maximum TEM00-mode Q-switched output energy of 10.9 mJ and a relatively long pulse width of 228 ns were obtained at a repetition rate of 15 Hz by use of a modified 2-m-long telescopic cavity. Frequency stability of as high as ±1.9-MHz standard deviation and a side-mode suppression ratio of more than 30 dB were also achieved.
