Fiber Coupling Module of High Brightness and High Power Semiconductor Laser
摘要
应用ZEMAX软件设计出高亮度大功率光纤耦合模块。采用16支输出功率12 W的单偏振态单边发射半导体激光器, 耦合进芯径100 μm、数值孔径0.22的光纤中。模块输出功率达到189.4 W, 耦合效率达到98.6%, 亮度达到94.66 MW/cm2-str。通过SolidWorks软件优化得到新热沉结构, 应用ANSYS软件进行热分析, 结果表明新热沉结构最高温度为42.4 ℃, 相比优化前温度降低1 ℃以上, 得到良好散热结构模型。
Abstract
In order to output light beam of higher power and higher brightness, the fiber coupled diode laser module consisting 16 single emitter semiconductor laser diodes with 12 W was designed by ZEMAX. This module can produce 189.4 W from a standard optical fiber with core diameter of 100 μm and numerical aperture of 0.22. The coupling efficiency is 98.6% and the brightness is above 94.66 MW/cm2-str. The new heat sink structure was designed by using SolidWorks software and the thermal analysis was simulated by ANSYS software. The results show that the hightest temperature of new heat sink structure is 42.4 ℃, 1 ℃ lower than before.
