摘要： When a wavelength of a first laser beam with which a first recording medium including a first recording layer is recorded and reproduced is indicated as λ1 (nm), a wavelength of a second laser beam with which a second recording medium including a second recording layer is recorded and reproduced as λ2 (nm), the relationship between the wavelength λ1 and the wavelength λ2 is set to be expressed by 10≦|λ1−λ2|≦120. The first recording layer has a light absorptance ratio of at least 1.0 with respect to the wavelength λ1. The light transmittance of the first recording medium with respect to the wavelength λ2 is set to be at least 30 in both the cases where the recording layer is in a crystal state and in an amorphous state. In order to record and reproduce the optical multilayer disk with the above-mentioned characteristics, a multiwavelength light source with the following configuration is used. Wavelengths of fundamental waves with different wavelengths from injection parts formed at one end of a plurality of optical waveguides, which satisfy phase matching conditions different from one another and are formed in the vicinity of the surface of a substrate, are converted simultaneously, and the first and second laser beams are emitted from emission parts formed at substantially the same position at the other end of the optical waveguides. This enables an optimum optical system for high density recording and reproduction to be obtained.

摘要： An optical wavelength converting device is provided with a LiTaO.sub.3 substrate, a plurality of inverted-polarization layers periodically arranged in an upper surface of the LiTaO.sub.3 substrate, and an optical waveguide crossing the inverted-polarization layers. The upper surface of the LiTaO.sub.3 substrate is directed toward a -X-crystal axis direction. The inverted-polarization layers are formed by exchanging Ta.sup.+ ions of the LiTaO.sub.3 substrate for H.sup.+ ions, and an extending direction of each inverted-polarization layer is inclined at an angle of .theta. degrees (6.ltoreq..theta..ltoreq.174) to the +C-crystal axis direction toward a -Y-crystal axis direction. The optical waveguide is formed by exchanging Ta.sup.+ ions of the LiTaO.sub.3 substrate and the inverted-polarization layers for H.sup.+ ions to set a refractive index of the optical waveguide higher than that of the LiTaO.sub.3 substrate. The optical waveguide extends in a +Y-crystal axis direction. Fundamental waves polarized in a transverse electric mode induce electric field directed in .+-.Y-crystal axis directions and are converted into second harmonic waves in the optical waveguide.

摘要： The wavelength tolerance of a frequency doubler is enhanced so as to perform stable operation. Further, with the use of this frequency doubler, a laser source can directly modulate a laser. A waveguide and a periodic domain inverted layer are formed on an LiTaO.sub.3 substrate of -C plate, and the waveguide is divided into a plurality of zones having different propagation constants. A fundamental wave inputted in the waveguide is converted into a harmonic wave in each of the zones, and is emitted as SHG light.

摘要： A wavelength conversion laser is provided with a solid-state laser having a cavity, and a wavelength converting element arranged within the cavity. The solid-state laser includes two or more types of laser crystals and oscillates solid-state laser light of multiple wavelengths. The wavelength converting element converts the solid-state laser light of multiple wavelengths into light of second harmonic waves and sum-frequency wave of multiple wavelengths and simultaneously generates the second harmonic waves and sum-frequency wave of multiple wavelengths. The wavelength conversion laser outputs converted wavelength light having a broad spectral width and low coherency, thereby enabling it to carry out highly efficient and stable high-output oscillation.
