ABSTRACT:
A laser-diode-pumped solid-state laser includes a semiconductor laser for emitting a pumping laser beam, a solid-state laser crystal of an ion crystal of a paramagnetic substance doped with neodymium, for producing a laser beam in response to being pumped by said pumping laser beam, a resonator for oscillating the laser beam produced by said solid-state laser crystal, and an optical wavelength converter in said resonator for converting the wavelength of the oscillated laser beam into another wavelength. The solid-state laser crystal has a neodymium ion concentration higher than 3 at %. The solid-state laser oscillates stably in a single longitudinal mode at all times to produce a highly intensive laser beam of short wavelength.
