EMPLOYMENT OF LASCAD PROGRAM TO STUDY THE THERMAL DISTRIBUTION ACROSS ND: YAG DISC PUMPED BY DIODE LASER

The most important characteristic of solid-state laser systems is the homogeneous distribution of the pumping beam within the active medium, which is also closely related to the design of the resonator. In addition, the efficiency of the cooling system, this is responsible for the exchange of heat between the active medium and the external environment..In this project, we hire LASCAD software to design and study the effect of thermal distribution across the disc laser when pumped by a laser diode. This parameter is more important when we want to design and contract of laser system because an inhomogeneous of that causes selffocusing and damage in active media.. We plotted and study this effect on laser system performance.
