摘要
本文叙述了一种新型的Nd:YAG激光器倍频系统,它主要用于诊断皮秒扫描/分幅变象管的静态及动态特性,亦可用于非线性光学和其它超快现象。最后讨论了影响谐波器件转换效率的一些参数。通过计算机模拟确定了这些参数的最佳值,从而使谐波器件的转换效率得到进一步提高。
A new Nd:YAG laser system is presented which offers wide application for diagnosing soft x-ray picosecond streak/framing cameras, nonlinear optics and other ultrafast phenomenna. Some very useful results of the cameras have been got by using this system. Finally we discuss some parameters of affecting harmonic conversion efficiency, such as phased-matched direction, maximal direction of the effective nonlinear coefficient and tureshold power. By computing simulation, we obtained optimal values of the parameters of the harmonic device. Thus, harmonic conversion efficiency of device has further up.
