美国加州Laser Poaer公司的D.E.Hargis等人提出一种新的激光内脏频率转换方法。此频率转换系统由增益介质、泵浦光源组成。泵浦光源发出的光激励光腔中的增益介质,转换发射激光频率产生沿光轴第一个方向传播的第一转换频率的光束,第二转换频率的光束沿光轴相反方向传播。并与光轴成一定角度反射第二转换频率光束。
D.E.Hargis and others of Laser Poaer Company of California of USA propose a new laser visceral frequency conversion method. This frequency conversion system consists of gain medium, pump light source. The light emitted by the pump light source excites the gain medium in the optical cavity, converts the transmitted laser frequency to produce a light beam of a first conversion frequency propagating in a first direction of the optical axis, and the light beam of the second conversion frequency propagates in the opposite direction of the optical axis. And reflects the second conversion frequency beam at an angle to the optical axis.
