加长棒脉冲钕玻璃激光器异常实验现象理论研究

The theoretical study on abnormal experimental phenomenon of the elongated rod Nd:glass pulsed laser

以激光原理为基础,以大量精确的实验数据为依据;考虑被忽略的自发辐射的影响,对加长到抽运腔外的钕玻璃棒,未受到抽运,反而产生光放大异常实验现象的机理进行了理论研究.理论研究结果与实验结果基本相符.

According to the principle of laser and a large number of experimental data proved and also considering the influence of the ignored spontaneous emisson, we study the abnormal phenomenon that the Nd： glass rod which was longer than the optical pump cavity is optically amplified without pumping. The theoretical result is almost the same as experimental result.
