1.9 μm laser pumped Ho: YAP acousto-optic Q-switched dual pulse laser
Utilizing dual-end pumping technology within semiconductor lasers, a continuous output of 0-18.92W was realized in a Tm: YAP laser, with a consistently measured central wavelength of 1989.01nm. Next, build a Ho: YAP acousto-optic Q-switched dual pulse laser resonator with a repetition rate of 1kHz, Ua=9V, Ub=6.5V, and Tb=2 μs. Tc=2 μs. When the pumping power is 18.92W, the maximum average power output of the Ho: YAP dual pulse laser is 1.89W, with a center wavelength of 2117.64nm and a line width of 0.64nm. The dual pulse laser is stable, with both pulse widths of 68.80ns and a pulse interval of 2 μs.
