Description

Technical field [0001] The invention relates to the field of LD pumped pulse single frequency Tm, Ho: YAP solid-state lasers. Background technique [0002] Differential absorption lidar and coherent Doppler wind measurement radar are powerful tools for real-time measurement of gas composition and atmospheric wind field. With high atmospheric transmission and transmittance, 2μm seed injection single-frequency pulsed solid-state laser is the high performance of the above-mentioned lidar Laser emission source. According to the atmospheric transmittance spectrum, the longer the wavelength of the 2μm laser under the same power, the longer the transmission distance, which is more conducive to increasing the measurement distance of the lidar. The 2μm solid-state laser device directly pumped by laser diode (LD) has the advantages of compact structure, stable performance and easy maintenance, which is very suitable for practical applications. LD-pumped Tm\Ho doping materials are an effe...
