摘要

激光照明光源具有高功率密度、高亮度、长寿命等优点，逐渐成为固态照明领域新的研究热点。激光光斑大小对正确评价激光荧光材料的光学性能具有十分重要的影响，然而一直以来领域内缺乏对这一问题的深刻而系统认知。本文以Y

∶Ce

-Al

(YAG∶Ce-Al

)荧光薄膜为例，通过对蓝光激光激发荧光薄膜的光斑尺寸的调控，系统研究了激光荧光材料的最大输出光通量、发光饱和阈值、色温、色坐标、光均匀性等光学性能随光斑面积的变化情况，揭示了光斑大小对最大输出光通量、发光饱和阈值以及光均匀性的显著影响，这将对规范激光荧光材料的性能评价提供指导性思路。

Abstract

The newly-emerging laser lighting technology shows great advantages of high brightness

high luminous flux and long lifetime

which therefore attracts more attention for use in high-beam headlamps

cinema projectors and endoscopy. In this technology

the size of laser spots has a large effect on the proper evaluation of laser phosphors

but it is usually neglected and lack of deep investigations. In this paper

we conducted a survey on the influence of the spot size on the maximum output luminous flux

luminous saturation threshold

color temperature

color coordinates

and light uniformity of Y

∶Ce

-Al

(YAG∶Ce-Al

) phosphor films for laser lighting. It reveals that the laser spot size does have a vital effect on optical properties of laser phosphors

and needs to be carefully considered. This work provides a general guideline for standardizing the performance evaluation of laser phosphors.
