摘要

蓝光半导体激光器激发荧光粉产生白光光源技术发展迅速,但由于大功率蓝光半导体激光器在快轴、慢轴方向的光场分布差别较大,使得日前激光照明整体光学性能仍旧较差,难以实现大规模推广应用。针对该问题,设计了一款高质量激光照明光学系统,基于蒙特卡洛光线追踪理论,对激光光束进行准直调控、均匀光斑整形以及对荧光片进行设计,使得整体光源模块各元件得到最佳整合,最终实现了窄光束激光照明。仿真结果表明:激光光源的光收集率达98.3%,激光光斑的不均匀度为1.7%,白光均匀度为98%,光斑是出射准直角为1.6°的方形窄光束白光光斑。

Abstract

The technology of the blue light semiconductor laser excitation phosphor to produce the white light source is developing rapidly. However, due to the large difference of the light field distribution in the fast axis and slow axis direction of the high-power blue light semiconductor laser, the overall optical properties of the laser illumination are still poor, which is difficult to achieve the large-scale application. Aiming at this problem, a high-quality laser illumination optical system was designed based on the Monte Carlo ray tracing theory. The collimation regulation of the laser beam was carried out, the uniform light spot was shaped, and the fluorescent sheet was designed, so that the components of overall light source modules obtained the optimal integration, and the narrow beam laser illumination was finally realized. The simulation results show that the light collection rate of the laser light source reaches to 98.3%, the ununiformity of the laser spot is 1.7%, the uniformity of the white light is 98%, and the light spot is the square narrow beam white light spot with an exit collimation angle of 1.6°.
