Abstract

A model has been developed to describe the dynamic behavior of radiation-balanced cw laser oscillators. We have derived algebraic equations and analytic expressions from the set of coupled rate equations and the requirements for radiation balance. The analytic expression predicts that the characteristics of a radiation-balanced laser are explicitly affected only by temperature, cavity parameters, and fundamental material properties. Several figures are generated from the derived expressions by use of Yb:KGW as an example. From these figures, the output characteristics of radiation-balanced laser oscillators are well revealed.
