摘要： A short wavelength light source is provided with a fundamental wave light source for generating a fundamental wave, and a plurality of wavelength conversion elements made of nonlinear optical crystals having periodic polarization-inversion structures and adapted to convert a part of the fundamental wave into a second harmonic, and the nonlinear optical crystals of the plurality of wavelength conversion elements are different in material or composition. By converting the fundamental wave from the fundamental wave light source by the plurality of wavelength conversion elements, the generation of a thermal lens effect caused by light absorption can be suppressed to improve a high output resistance.

摘要： A 2-dimensional beam scan unit (2) reflects emission beams from a red laser light source (1a), a green laser light source (1b) and a blue laser light source (1c) and scans in a 2-dimensional direction. Diffusion plates (3a, 3b, 3c) diffuse the respective light beams scanned in the 2-dimensional direction to introduce them to corresponding spatial light modulation elements (5a, 5b, 5c). The respective spatial light modulation elements (5a, 5b, 5c) modulate the respective lights in accordance with video signals of the respective colors. A dichroic prism (6) multiplexes the lights of the three colors after the modulation and introduces the multiplexed lights to a projection lens (7) so that a color image is displayed on a screen (8). 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.
