Abstract
A single-frequency diode-pumped Q-switched Er,Yb:phosphate glass laser that oscillates at an eye-safe 1.54-mum wavelength has been developed for use i n 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 repe tition rate of 15 Hz by use of a modified 2-m-long telescopic cavity. Frequ ency stability of as high as +/-1.9-MHz standard deviation and a side-mode suppression ratio of more than 30 dB were also achieved. (C) 2001 Optical S ociety of America.
