    摘要： An object of disclosed technology is to control lasing wavelengths so that a wavelength shift does not occurs. Another object is to permit wavelengths of a light source for wavelength division multiplexing optical-fiber communication system to be variable in response to an ITU-TS grid. A means for achieving the objects is as follows: locating an etalon in a light path of diode laser light, which is a parallel plane wave changed by a collimator lens; generating a wavelength error signal from a difference between both of divided pieces of light from transmitted light or reflected light; and locking a wavelength of a diode laser device according to the wavelength error signal.

    摘要： A short-wavelength laser having a stable output and an optical information processing system capable of high-density recording are disclosed. A solid-state laser is used as a light source, and a nonlinear optical crystal is arranged in a resonator in order to produce a short wavelength by means of a solid-state laser. The retardation of the nonlinear optical crystal is controlled by determining the length of the nonlinear optical crystal. A solid-state laser device having a stable output with the noise removed from a pumping power light source is also provided. Further, the solid-state laser device is used as a light source for the optical information processing system, and the light of irrelevant wavelengths contained in the light from the solid-state laser device are removed by a device having the ability to select wavelengths. Thus, not only a stable light source with a short wavelength but also an optical information processing system capable of high-density recording are realized.
