摘要： A laser diode pumped solid laser comprises an optical module comprising a laser diode, a solid laser crystal, which is excited by a laser beam produced by the laser diode, and a resonator. An electronic cooling device has a cooling surface, on which the optical module is placed, and a heat radiating surface.

An outer case housing houses the inner case housing and the electronic cooling device therein and supports the electronic cooling device via its heat radiating surface. A temperature sensor detects the temperature in the region inside of the inner case housing. A control circuit controls the electronic cooling device in accordance with an output of the temperature sensor and thereby keeps the temperature in the region inside of the inner case housing at a predetermined target value.

摘要： A laser diode pumped solid laser comprises a solid laser medium, to which a rare earth metal has been added, a semiconductor laser, which produces a laser beam for pumping the solid laser medium, and a condensing lens, which causes the laser beam to converge in the solid laser medium. The condensing lens is located such that an optical axis of the condensing lens may deviate in the width direction of a semiconductor laser active layer from a center of irradiation area of the semiconductor laser. The amount of light returning to the semiconductor laser is thereby reduced markedly, and good stability in the output power of the laser diode pumped solid laser is obtained. A nonlinear optical material for converting the wavelength of a laser beam, which has been produced by the solid laser medium, into a different wavelength may be located in a solid laser resonator.
