We designed a high power diode-side-pumped single head Nd:YAG laser. Utilizing a reflective optical cavity we enhanced the pumping system. Using ray tracing and Monte Carlo methods, the absorbed power distribution and absorption efficiency were investigated and the best configuration for the head module including reflector dimension and rod diameter were studied. Regarding to obtained parameters, an output power of 588 w were acquired for the plane-parallel resonator of length 140mm and optimum output coupler reflectivity of 80%.This correspond to the optical-optical efficiency of 32.9% and slope efficiency of 47.7% for our designed pumping system. The laser was operated for 100 hours and no degradation was observed for the output power.
