| 摘 要： | 利用光学软件ZEMAX优化设计并实际制作了一种可用于激光二极管阵列(LDA)快慢轴同时准直的新型准直器件,这种准直器利用三维精密调节系统对D型光纤的侧面进行刻蚀,在D型光纤的纵向上形成一个微型柱透镜阵列,其折射率与光纤折射率相同.利用这个微型柱透镜阵列对激光二极管阵列的慢轴进行准直,同时利用D型光纤横向上D型结构对激光二极管阵列的快轴进行准直.准直后的光束发散角为1.82 mrad×10.4 mrad,功率损失在10%以下.

| Abstract: | A novel collimator for collimating the fast and slow axis of laser diodes array(LDA) simultaneously is designed optimized by ZEMAX and also fabricated by using a precise three-dimensional control actuator to erode the side of a D-type fiber.This collimator consists of a D-type fiber with a series of longitudinal cylindrical lens array which has the same refractivity as fiber and acts as the slow axis collimator for LDA.Meanwhile,the D-type fiber is also able to collimate the fast axis of LDA with its transverse D-type structure.Experimental results show that the angles of divergence of fast and slow axis are 1.82 mrad and 10.4 mrad respectively after collimation.The power loss is less than 10%. |
