Abstract: An illumination light source is provided with a laser light source having a laser medium with a specified gain region, and a reflector having a narrow band reflection characteristic. A part of a laser light emitted from the laser light source is reflected and fed back by the reflector, so that an oscillation wavelength of the laser light source is fixed at a reflection wavelength. A peak of the gain region of the laser medium is shifted from the reflection wavelength by a change of an oscillation characteristic of the laser light source, so that the oscillation wavelength of the laser light source is changed from the reflection wavelength. Thus, an oscillation spectrum of the laser light source is spread to reduce speckle noise.

Abstract: A short wavelength light source of the present invention comprises a nonlinear crystal having a periodical polarization reversal structure. The polarization reversal structure of the nonlinear crystal is divided into a plurality of regions and the polarization reversal structure and the optical axis of the fundamental wave are inclined with different angles in the respective regions, so that higher harmonic generated is divided into a plurality of beams. By dividing the higher harmonic component into a plurality of beams, it is possible to reduce the power density of the higher harmonic and generate walk off in the fundamental wave and the higher harmonic, thereby to suppress generation of the sum frequency waves of the fundamental wave and the higher harmonic so as to enhance the tolerance to high output. Therefore, SFG generation is suppressed, and a high output power coherent light source is realized.

Abstract: A measuring substance (2) is excited by light emitted from a light source (1), fluorescence generated from the substance (2) is directed to transmission-type band-pass filters (4, 6, 8) sequentially, and light having a specific wavelength that has passed through the band-pass filters (4, 6, 8) is detected by light-receiving portions (5, 7, 9). Differences or relative ratios between the signal strengths detected by the respective light-receiving portions (5, 7, 9) are measured to determine a peak wavelength of the fluorescence spectrum, thus identifying the substance (2). With this configuration, a fluorometer can achieve a small size, low cost, and short-time detection.

Abstract: In a laser display that displays a video by scanning a beam from a laser light source two-dimensionally on a screen, the image quality being displayed is deteriorated markedly by speckle noises induced from coherency of the light source. A method for oscillating the screen to remove the speckles has problems that a large-scale device is necessary and the screen cannot be chosen without any restrain.A speckle pattern being generated is changed at a high speed by oscillating a light spot on the screen at a high speed using beam oscillation means 3, so that the viewer acknowledges time-mean image having no speckle noises.

Abstract: After forming domain inverted layers 3 in an LiTaO.sub.3 substrate 1, an optical waveguide is formed. By performing low-temperature annealing for the optical wavelength conversion element thus formed, a stable proton exchange layer 8 is formed, where an increase in refractive index generated during high-temperature annealing is lowered, thereby providing a stable optical wavelength conversion element. Thus, the phase-matched wavelength becomes constant, and variation in harmonic wave output is eliminated. Consequently, with respect to an optical wavelength conversion element utilizing a non-linear optical effect, a highly reliable element is provided.

Abstract: In the video projector of the present invention, a fiber part (3b) of a fiber laser (3) is disposed so as to draw a circulating orbit of more than one circulation along the inner wall of the projector housing (1). Further, an FBG (14) which constitutes the fiber laser (3) is fixed so that its shape is not changed. Furthermore, a pump LD part (3a) of the fiber laser (3) is disposed apart from the SHG element (5). As a result, the video projector can be miniaturized, and thereby the portability and installment of the video projector are facilitated. Further, the output stabilization of the fiber laser can be realized by preventing the shape change of the FBG. Furthermore, by disposing the SHG element apart from the pump LD part which forms a heat source, the temperature change of the SHG element is suppressed and the wavelength conversion efficiency by the SHG element is enhanced.
