摘要
为了突破多单发射区半导体激光器光纤耦合模块设计过程中空间合束法遇到的合束功率及光功率密度无法上升的瓶颈,得到多单发射区半导体激光器光纤耦合模块更优参数的光束输出,同时完成单一激光器光纤耦合模块泵浦多种激光器的目标,结合ZEMAX光学设计软件及Solidworks工程设计软件设计并制作了一种由6支、可输出2种波长分别为915 nm及974 nm的单发射区半导体激光器组成的光纤耦合模块。该模块的实现过程包括微透镜光束快慢轴整形、空间合束、波长合束、光路转向及聚焦,最终耦合进数值孔径为0. 22、光纤芯径为105μm的普通光纤,测试结果表明该模块光纤输出光功率达到了46 W,2种波长均在光纤输出光束中检测到,且光纤耦合效率高于83%。使用ANSYS软件对模块进行散热分析,结果显示,模块正常使用后最高温升至37℃,在正常使用温度范围内,表明模块的散热性能良好,具备实际应用的可行性。
A practical method of a high optical power density and high power fiber-coupled laser diode module based on six single-emitter semiconductor laser diodes at 915 nm/974 nm was demonstrated by ZEMAX software simulation and experiments.To obtain a high power and high optical power density laser beam,which included two wavelengths for pumping two kinds of solid lasers or fiber lasers by the same module,the optical reshaping,spatial multiplexing and wavelengths multiplexing were used in this module to combine six single emitters into a single beam.Then,an aspheric lens was used to couple the combined beam into an optical fiber.This module can produce more than 46 W output power with coupling efficiency of 83%from a standard multi-mode optical fiber with core diameter of 105μm and numerical aperture(NA)of 0.22.
