摘要
高功率蓝光半导体激光可广泛应用于高反射高导电材料的加工中。阐述了一种高效紧凑的高功率高亮度蓝光半导体激光光纤耦合的实现方法,将27只蓝光单管组成3×9阵列并耦合进100μm/NA0.2的光纤中。研制出的光纤耦合模块可实现450 nm波段蓝光LD输出,功率约75 W,电光效率约28%,还可采用偏振合束进一步提升光纤耦合激光功率。
Based on the advantages of diode laser,such as high efficiency and high integration,blue diode laser source can be widely used in highly-reflective and highly conductive materials processing.This paper introduces a high power high brightness blue diode laser fiber coupling module based on 3×9 single emitter diode laser array,which can realize 75 W single polarization 450 nm diode laser output from 100μm 0.2 NA fiber.Polarization beam combining can also be used to further improve the fiber coupling blue diode laser power.
