The new crystal of NYAB (neodymium yttrium aluminum borate) is presented. The optical and mechanical properties, crystal structure and growth of this crystal is investigated. Performance of emissions at 1063 nm and 532 nm is presented for both flash-lamp-pumped (pulsed) and dye-laser and diode-laser pumped (cw). A comprehensive model for intracavity doubling including the dopant-dependent gain and absoprtion (loss) is also analyzed. In this paper, we denornstrate the first experimental results of diode-pumped NYAB with green ligth output power in the 10 μW range.
