摘要
激光显示作为新一代的显示技术,有着传统显示方式无法比拟的优势,而红绿蓝三基色/准白光激光器则是激光显示技术的基础。三基色激光可以通过多种技术获得,通过非线性频率转换技术获得三基色激光是其中的一种。基于准位相匹配技术的光学超晶格作为非线性晶体通过微结构的设计能同时完成多个光参量过程。把光学超晶格多波长频率转换功能和全固态激光技术结合在一起,可以实现红绿蓝三色激光的同时输出。在此基础上,通过控制三色光的功率比例还可以获得白光的视觉效果,可称为准白色激光。本文介绍了我们在这一方面的初步工作,并对这一领域的发展作了一些展望。
As the next generation of display technique, laser based display has more advantages than the conventional ones and red, green and blue （RGB）, the three primary colors, are the base. Using nonlinear frequency conversion technique is one of the ways to obtain RGB. Optical superlattiee based on quasi-phase-matehing theory is frequently used as nonlinear frequency converter due to the flexible design and simultaneous phase-matching of multiple optical parametric processes. Combining optical superlattiee with all-solid-state laser technique, we can get simultaneous RGB output, and by weighted combination of RGB, quasi-white light could be obtained. In this paper, we will introduce our preliminary work in this area and give some future directions.
