摘要： In a laser light source apparatus using a wavelength converting device (35), the position and angle of the wavelength converting device are allowed to be varied so as to maximize the laser output. The angular adjustment of the wavelength converting device is simplified by accurately positioning the wavelength converting device. A holder (57) for retaining the wavelength converting device may be supported by a support portion (56) formed in a base (38) so as to be moveable in the depthwise direction of the poled inverted domain regions and tiltable with respect to the optical path. Preferably, the holder may be rotatable around an axial line substantially perpendicular to the optical axial line. In particular, the wavelength converting device may be fixedly attached to the holder so as to bring an exit surface (35b) of the wavelength converting device in close contact with a mounting reference surface (841) by using a bonding agent applied to a top surface (35e) and a bottom surface (35f) of the wavelength converting device adjacent to the exit surface, and a bottom surface (207) of a recess (891) formed in the holder adjacent to and in parallel with the mounting reference surface.

摘要： A laser light source 1 outputs a laser. A condenser lens 80 condenses the laser outputted from the laser light source 1, and outputs it to an optical fiber 8. The laser that propagates through the optical fiber 8 enters a light guide panel 2. The light guide panel 2 converts the inputted laser into a planar illumination light. The planar illumination light passes through a light passing control section 4 and illuminates a liquid crystal panel 7, which is a spatial modulation element that convert light into an image. The light passing control section 4 controls a scatter pattern during the passing of the laser individually in each predefined image area, by a control circuit 81. Consequently, an image area 5 in which a speckle noise is reduced and an image area 6 in which the speckle noise is generated, are formed on a liquid crystal panel 7.

摘要： A wavelength detector capable of distinguishing between the changes of a transverse mode and of a longitudinal mode of a laser light and thus detecting the change of the wavelength of the laser light with high accuracy is provided. In a wavelength detector 13: a diffraction grating 16 diffracts a laser light emerging from a laser light source 10; photodetectors 50a and 50b are positioned symmetrically with respect to a 0-order diffracted light diffracted by the diffraction grating 16; and light incidence surfaces 51a and 51b of the photodetectors 50a and 50b, respectively, have the same shape and are each divided into a plurality of areas. The wavelength detector 13 detects the change of the wavelength of the laser light based on a value obtained by dividing the difference value between the sum of light intensities measured by all of the plurality of divided areas of the photodetector 50a and the sum of light intensities measured by all of the plurality of divided areas of the photodetector 50b, by the sum of light intensities measured by all of the plurality of divided areas of the two photodetectors 50a and 50b.
