Abstract :
Microlasers consisting of monolithic, Fabry-Perot resonators are known to rely on pump-induced thermal guiding to generate diffraction-limited beams. Finite-element analysis has been applied to the problem of modeling thermal effects in diode-laser-pumped microlasers for the purpose of predicting near-field patterns, local temperatures, and fracture margins. Estimates of the fundamental-mode radii in Nd:YAG and Tm,Ho:YLF linear microlaser arrays are compared to experimental data
