摘　　要：将输出光谱包络合理近似为高斯型,以高斯算法为基础,利用计算机软件编写了激光器阵列光谱合成模拟软件,实现了对激光器阵列合成波长、半高宽以及光谱图形的模拟。结果表明:用软件进行光束合成的激光器阵列波长与实际测试的波长基本吻合,但存在一定误差。基于这种情况,对模拟结果和实测结果的误差部分进行分析实验,以验证误差分析的正确性,并将误差重新编写到软件。该模拟软件可以在激光器组装阵列之前对激光器单条进行筛选,找出符合组成阵列波长要求的最佳激光器单条,使得实际生产出的激光器阵列波长与阵列的设计波长基本一致。With the high-power semiconductor laser diode array and its applications becoming widespread, spectral purity research of high-power semiconductor laser as the pump source in related fields has become one of the hotspots. The spectrum envelope is reasonably approximated Gaussian. The laser diode array spectrum synthesis simulation software is compiled taking the Gaussian algorithm as the foundation, which achieves a synthesis of the wavelength of the laser array, as well as the full wave at half maximum of the analog spectrum graphics and simulation. Simulation results shows that there is a difference between the simulated and the actually tested wavelength values. The difference is analysed for verification and then used to modify.
