In this paper, a precise simulation is performed for thermal effects of the side diode-pumped laser slab by using ZEMAX and LASCAD programs. First, by considering all details of pumping structure such as number of laser diode bars, distances, their pump distribution and divergence angles, ray tracing and absorbed pump density into the slab are simulated by ZEMAX. Then, the absorbed pump data file, obtained from ZEMAX, is entered into LASCAD. The thermal effects are analyzed by defining of material parameters, slab dimensions, cooling conditions and meshing structure in this software. Simulation results include temperature and stress distribution (Two-dimensional and three-dimensional), deformation and focal length of thermal lens. To certify the value of the simulation, the thermal effects results of laser slab are compared for different pump powers and coefficients of force convection heat transfer.
