Paper Abstract

A coherent Doppler lidar is a useful sensor for wind velocity detection in clear air condition. A stable single frequency and relatively long Q-switched pulse width (~200 nsec order) in eye-safe wavelength range (>1.4 ?m) is required for a composed pulsed laser. For these requirements, we have developed an injection-seeded diode-pumped Q-switched Er,Yb:glass laser which oscillates at 1.54 ?m. The maximum laser output energy of 10.9 mJ and the pulse width of 228 nsec were obtained. A stability of the pulsed laser output frequency was less than +/-1.9 MHz standard deviation from the seeded light frequency.
