CW-pumped Nd:YVO4 lasers passively Q-switched with View the MathML source and YAG:Cr4+ saturable absorbers are modeled and comparatively analyzed. The model takes into account the geometric factor representing the distributions of the orientations of View the MathML source color centers and Cr4+ ions relatively to the corresponding crystalline hosts on the output parameters of the lasers. It is shown that the View the MathML source Q-switch has evident advantages over the YAG:Cr4+ one in the senses of a much more expanded range of pump powers where the giant-pulse regime is supported in the laser and, as a consequence, potentially higher average output and peak pulse powers accessible.
