摘要: 为了提高微柱阵列与透镜导管耦合系统的光斑整形效果,设计了一种横截面是椭圆、且椭圆离心率随位置变化的不规则导管设计方案。在导管的前端面,椭圆长轴在水平方向,以与激光二极管阵列的发光面形状相匹配;在导管后端面,椭圆长轴逐渐过渡到竖直方向。利用3维光线追迹方法进行仿真计算,可知该不规则导管可以得到圆对称性较好的光斑整形效果,微柱阵列和该导管的能量传输效率分别为90.84%和91.98%,对应于整个耦合系统的能量传输效率为83.55%。结果表明,该不规则导管在光斑整形效果和能量传输效率方面与普通导管相比具有一定优势。

Abstract: In order to improve the facular-shaping effect of the microcylinders and lens duct, a new duct with changing elliptical cross section was proposed. The long axis of the ellipse on the front surface is located in horizontal direction, which matches the light emitting distribution pattern, The long axis of the ellipse on the back surface gradually become in vertical direction. The 3-D ray-tracing simulation indicates that the irregular duct can achieve relatively good circular symmetric pumping energy distribution. The energy transferring efficiency of microcylinders and the duct is calculated to be 90.84% and 91.98% respectively, corresponding to the total efficiency of 83.55%. The contrast indicates that the irregular duct possesses some advantages in facular shaping and energy transferring efficiency over common ducts.
