    • A second harmonic generation device has a waveguide layer for generating and outputting a second harmonic wave ray in response to the laser light from a laser, wherein the returning of reflected laser light from the waveguide layer to a laser is prevented. The returning of reflected laser light is prevented: by inclining a normal of at least one of a first and second end facets of the waveguide layer from an optical axis of the laser; by providing an absorbing layer on the waveguide layer for absorbing waveguided laser light and for waveguiding the generated second harmonic wave ray; or by providing a second waveguide layer for waveguiding and outputting the generated second harmonic wave ray and for radiating the waveguided laser light. The absorbing layer is provided by a blue filter adhered or deposited on the top surface of the waveguide layer. The second waveguide layer is provided by making the second waveguide layer more narrow that the waveguide layer. A second harmonic generation apparatus includes the laser. Methods of producing these devices and apparatus are disclosed.

    • 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.

    • An image processing area is divided into a plurality of small areas which are allowed to overlap one another. One or a plurality of pixels in a region to be segmented and in a region not to be segmented are specified. A representative point of the region to be segmented and a reference point of the region not to be segmented are determined from the color information of each of the pixels. A discriminating plane, a plane or a curved surface that intersects the line segment connecting the representative point and the reference point a right angles is used in processing. By the processing a particular region can be segmented out of the image. Further, a shape model is made by two-dimensionally projecting from a given direction the three-dimensional structure expressed by a line drawing consisting of nodes and curves connecting the nodes based on priori property relating the structure of the region to be segmented in the image. The shape model is then roughly correlated in position with the nodes on the contour of the image. An image processing provides stripe images having widths for each of the curves that is recomposed and used to find the contour and structure of the object in detail.
