【 摘 要 】

Report the acousto-optical Q-switched operation of double ended pump big energy Tm:YAP laser.Tm:YAP crystal was a-cut, the dimensionas were 3mm×3mm×15mm and doped was 3at%. The laser diode center wavelength of 795nm. When the pump power was 79.2W, the repeat frequency was 1 kHz, a 1.99 μm wavelength laser output of up to 16.36 mJ was obtained, the narrowest pulse width of 38.04 ns, the peak power of 430.07 kW. The slope efficiency was 29.42%, light and light conversion efficiency was 20.66%. When the Q-switched average power was 15W, the beam quality factor of M2 was estimated of 3.19 in x-direction and 3.29 in y-direction.
