We evaluated characteristics of various shapes of reflector to get uniform and efficient pumping of Nd:YAG rod even with single-side pumping geometry using commercial software ZEMAX and LASCAD. The combined application of the software enabled us to evaluate numerically the laser performance and absorbed pump diode profile. We tried various shape of reflector such as semi-circular, square, elliptical reflectors, and cusp-shape, to get uniform pumping. In the calculation, water flows inside the cooling tube which surrounds the Nd:YAG rod. For further improvement a planarconcave window was placed in front of the diode to enlarge pump beam divergence angle. Through several trial and error, we found optimal pumping chamber configuration for single-side pumping, which gives reasonably uniform and efficient pumping of Nd:YAG rod. The output power and pulsewidth of Q-switched laser output were optimized by varying the laser cavity length and the output coupler reflectivity.
