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： A short-wavelength light generating apparatus comprising a pumping semiconductor laser and an intra-cavity solid state laser, the intra-cavity solid state laser is excited in response to a laser light beam from the semiconductor laser to generate a short-wavelength light beam to an external. Also included in the apparatus is an external grating mirror having on its one surface a reflection type diffraction grating and placed between the semiconductor laser and the intra-cavity solid state laser. The external grating mirror reflects the laser light beam from the semiconductor laser to feedback a portion of the laser light beam to said semiconductor laser so that an oscillated wavelength of the semiconductor laser becomes within a wavelength acceptance of the intra-cavity solid state laser. Further, the external grating mirror supplies a portion of the laser light beam from the semiconductor laser to the intra-cavity solid state laser. This arrangement can output a stable harmonic wave with a high efficiency.

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.

摘要： A 2-dimensional beam scan unit reflects emission beams from a red laser light source, a green laser light source and a blue laser light source and scans in a 2-dimensional direction. Diffusion plates diffuse the respective light beams scanned in the 2-dimensional direction to introduce them to corresponding spatial light modulation elements. The respective spatial light modulation elements modulate the respective lights in accordance with video signals of the respective colors. A dichroic prism multiplexes the lights of the three colors after the modulation and introduces the multiplexed lights to a projection lens so that a color image is displayed on a screen. Since the 2-dimensional light emitted from the beam scan unit is diffused to illuminate the spatial light modulation element, it is possible to change the optical axis of the beam emerging from the light diffusion member for irradiating the spatial light modulation element moment by moment, thereby effectively suppressing speckle noise.
