The spectroscopic and thermal properties of the trivalent neodymium doped YAG ceramic polycrystal line are analyzed in detail and cw operation of a diode-pumped microchip laser is reported. Strong absorption coefficient at 808 nm and large thermal conductivity are realized in the highly Nd-doped YAG ceramic polycrystal line. Up to 122 mW output power 24.5% slope efficiency was obtained on the 4.8 at.% Nd-doped YAG ceramic microchip laser, which corresponded to four times enhancement of the 0.9 at.% Nd:YAG single crystal microchip laser.
