Abstract

In order to develop an efficient eye-safe laser, operating in the 1.53 μm region, we have written software that models the performance of a passively Q-switched Er:Yb:glass laser with a divalent cobalt Co²⁺:spinel saturable absorber. At present a 0D model, which uses a plane-wave approximation, has been completed. The model is based on a set coupled first order differential equations that describe the laser dynamics. These equations represent a two-level Yb³⁺ diode pump scheme, a five-level Er³⁺ gain medium, and a four-level Co²⁺ Q-switch. The model takes into account cooperative upconversion and excited state absorption (ESA) in both the gain and absorber media. Solutions to the rate equations and optimization examples are presented.
