Comparative study of the optical pumping efficiency in solid-state lasers
Abstract
The optical pump efficiency of a solid-state laser is calculated as a product of four factors: the lamp radiative efficiency, the transfer efficiency of the pump cavity, the absorption efficiency of the rod, and the power quantum efficiency of the active material. Explicit expressions are calculated for these factors with respect to the five active materials: ruby, Nd:YAG, Nd:glass, alexandrite, and Cr:Nd:GSGG, under typical operating conditions. The computed values are critically compared to the corresponding values to be derived from the experimentally measured slope efficiencies. The agreement between the calculated and experimental determination of the overall pumping efficiency is generally good.
