Abstract
A miniaturized, frequency-doubled blue laser utilizing a pump source operating within a radiation band of 780 to 820 nm, such as a Ti:sapphire laser or other suitable optical pump, to pump a gain medium comprising a crystal of neodymium-doped yttrium orthoaluminate (Nd:YAlO.sub.3) and produce a fundamental radiation having a wavelength of approximately 930 nm, the fundamental radiation being subsequently frequency doubled by means of a nonlinear crystal, such as potassium niobate (KNbO.sub.3), to yield output radiation at a wavelength of 465 nm.
