利用三维坐标变换矩阵的方法研究了捕获跟踪瞄准系统的精跟踪图像和角误差量随方位轴和俯仰轴的具体旋转变换关系,正确指导了精跟踪图像和角误差量处理工作,确保实现高精度稳定跟踪。

We present a near diffraction-limited 1 064-nm Nd:YAG rod laser with output power of 82.3W(M2 \approx 1.38). The power fluctuation over two hours is better than \pm 1.1%. Pulsed 1 064-nm laser with an average power of 66.6 W and pulse width of 46 ns are achieved when the laser is Q-switched at a repetition rate of 10 kHz. The short pulse duration stems from the short cavity as well as the high-gain laser modules. Using intracavity-frequency-doubling, a 35.0-W near diffraction-limited 532-nm green laser (M2 \approx 1.32) is achieved with a pulse width of 43 ns.
