1. A passively Q-switched (P-QS) laser, comprising:
a gain medium comprising a gain medium crystalline (GMC) material that includes a ceramic neodymium-doped yttrium aluminum garnet (Nd:YAG);
a saturable absorber (SA) rigidly coupled to the gain medium, the SA comprising a ceramic saturable absorber crystalline (SAC) material selected from the group of doped ceramic materials consisting of a three-valence vanadium-doped yttrium aluminum garnet (V3+:YAG) and two-valence Cobalt-doped crystalline materials;
an undoped YAG shaped as a cylinder encircling the gain medium and the SA for preventing heat from accumulating in an absorptive region of the gain medium; and
an optical cavity within which the gain medium and the SA are positioned, the optical cavity including a high reflectivity mirror and an output coupler.
