  • At present, 1.5 m LD pumped Er-glass passively Q-switched micro-laser is a popular research direction in military laser ranging. Achieving high repetition rate and single pulse energy are very important indicators. In this paper, a kHz erbium-ytterbium co-doped phosphate glass passively Q-switched microchip laser for laser ranging was reported. The laser was pumped by a single diode with a center wavelength of 940 nm and erbium-ytterbium co-doped phosphate glass (Er3+,Yb3+:glass) as the gain medium, CO2+:MgAl2O4 (CO:MALO) as the saturable absorber. By analyzing the influence of the pump spot radius on the mode-matching, the pump spot radius was optimized. The effects of the initial transmittance (T0) of saturable absorber and the reflectance R of output mirror on the output laser parameters were experimentally analyzed. In the final pre-pumping experiment, a Q-switched pulse was achieved, with repetition frequency of 1 kHz, wavelength of 1 535 nm, single pulse energy of 40 J, pulse width of 5.09 ns, peak power of 7.89 kW and beam quality of 1.4.

Achieving high repetition rate and single pulse energy are very important indicators. In this paper, a kHz erbium-ytterbium co-doped phosphate glass passively Q-switched microchip laser for laser ranging was reported. The laser was pumped by a single diode with a center wavelength of 940 nm and erbium-ytterbium co-doped phosphate glass (Er3+,Yb3+:glass) as the gain medium, CO2+:MgAl2O4 (CO:MALO) as the saturable absorber. By analyzing the influence of the pump spot radius on the mode-matching, the pump spot radius was optimized. The effects of the initial transmittance (T0) of saturable absorber and the reflectance R of output mirror on the output laser parameters were experimentally analyzed.
