Modeling of a solid-state laser module with pulse transverse diode pumping of Nd³⁺:YAG active medium

In this work, a laser module (quantron) with transverse pulse diode pumping of a cylindrical Nd3+:YAG active element by the method of non-sequential ray tracing in the Zemax software environment is modeled. Numerically obtained distributions of the absorbed pump radiation power over the cross section of the active element and calculated the pumping efficiency of the quantron. A methodology for optimizing the quantron design is proposed, which results in an increase in the pumping efficiency of the active element.
