在掠入射Nd：YVO_4激光器中获得了高达1 MHz的声光调Q运转。在重复频率为500 kHz时，当抽运功率为38 W时，采用32.4%的透射率输出耦合器，获得了17.7 W的激光输出。光束质量因子被测量为在X轴方向上M2 x < 4并且在y轴方向上M2 y < 2。对于高稳定性的声光脉冲运转，采用5%透过率的输出耦合器，在泵浦功率为38 W时获得了9.15W的输出功率。在489.6kHz重复频率下，脉冲幅度的峰-峰不稳定度小于±3.3%。
Up to 1 MHz acousto-optics Q-switching operation was obtained in a grazing-incidence Nd:YVO4 laser. At 500 kHz repetition rate, 17.7 W of output power was obtained with 38 W of pump power when 32.4% transmissivity output coupler was used. The beam quality factors were measured as M2x < 4 in the x-axis direction and M2y < 2 in the y-axis direction. For high sable acousto-optics pulse operation, 5% transmissivity output coupler was used and 9.15 W of output power was obtained at 38 W of pump power. The peak-to-peak instability of pulse amplitude was less than ±3.3% at 489.6 kHz repetition rate.
