摘要： After forming domain inverted layers 3 in an LiTaO3 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 nonlinear optical effect, a highly reliable element is provided.

摘要： Conventionally, in a display device using lasers, a blue light source having a relatively long wavelength and a red light source having a relatively short wavelength are adopted because a short-wavelength blue light source and a long-wavelength red light source cause degradation in visibility. Therefore, there are problems that an expressible color region is restricted, and large output power is required for white display. Accordingly, in a two-dimensional image display device of the present invention, the center wavelength of a red color source is set in a range from 635 nm to 655 nm and the center wavelength of a blue light source is set in a range from 420 nm to 455 nm, thereby obtaining a bright and clear image at minimum power consumption.
摘要翻译：通常，在使用激光的显示装置中，采用具有较长波长的蓝色光源和具有较短波长的红色光源，因为短波长蓝色光源和长波长红色光源导致可见性降低。因此，存在可表现的颜色区域被限制的问题，并且白色显示需要大的输出功率。因此，在本发明的二维图像显示装置中，将红色源的中心波长设定在635nm〜655nm的范围内，将蓝色光源的中心波长设定在420 nm至455nm，从而以最小功耗获得明亮清晰的图像。

摘要： An optical pickup and an optical information recording/reproducing device are provided, each of which is capable of forming a super-resolution spot to conduct micro-mark recording, and does not undergo signal degradation due to an increased sidelobe in a reproducing operation. A variable phase filter having three regions to produce a phase difference in a radial direction is used, to provide a phase difference of π between the center region and the side regions in a recording operation, so that a super-resolution spot is formed on a recording layer of the optical disk. In a reproducing operation, a phase difference is nullified between the regions of the variable phase filter, so that a normal light spot at a diffraction limit having a smaller sidelobe is formed. The variable phase filter can be formed with a homogeneous-alignment liquid crystal element.
