Abstract
A laser-diode-pumped solid-state laser includes a solid-state laser rod pumped by a pumping laser beam emitted from a semiconductor laser. The laser beam produced by the solid-state laser rod is oscillated by a resonator, and the wavelength of the oscillated laser beam is converted into another wavelength by an optical wavelength converter. The resonator is jointly provided by the solid-state laser rod and the optical wavelength converter. Alternatively, the solid-state laser rod may comprise a self-frequency-doubling crystal for producing a laser beam, oscillating the laser beam, and converting the wavelength of the oscillated laser beam into another wavelength. The temperature of the semiconductor laser and the resonator is regulated by a common temperature regulating device which comprises a Peltier device controlled by a driver circuit. Since the semiconductor laser and the resonator are regulated in temperature by the common temperature regulating device, no thermal interaction occurs between the semiconductor laser and the resonator.
