加长棒脉冲钕玻璃激光器光放大现象机理的探讨

The Study of the Phenomenon that the Optical Power of the Elongated Rod Nd∶glass Pulsed Laser is Amplified

以四能级激光系统的速率方程为基础 ,考虑自发辐射的影响 ,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现象的机理进行了理论探讨和实验验证。

Basing on the four level laser rate equations and the spontaneous emisson, we studied and demonstrated the phenomenon that the Nd∶glass rod which was longer than the optical pump cavity was potical amplified without the effect of the pumping. The result of the theoretical study is almost the same as that of the experiment.
