介绍了辐射平衡激光器原理以及谐振腔模型,并对腔内激光和泵浦光满足的方程进行了推导。计算了在Yb:KYW辐射平衡激光器谐振腔中激光和泵浦光光强的变化规律,以及输出端耦合镜反射率和腔长变化时带来的影响。讨论了腔长的最小值与输出端耦合镜反射率之间的关系。
The principle of the radiation balance laser and the cavity model are introduced, and the equations for the cavity laser and pump light to be satisfied are deduced. The variation of laser intensity and pump light intensity in Yb: KYW laser cavity and the influence of coupling mirror reflectivity and cavity length on output are calculated. The relationship between the minimum cavity length and the output coupling mirror reflectivity is discussed.
