建立了高能固态激光阵列合成的模型,对相干合成型和非相干合成型的高能固态激光系统进行了分析和比较。引入光束传输因子(BPF)作为评价合成光束的光束质量,对湍流大气对板条激光器和光纤激光器相干合成与非相干合成远场光束质量的影响进行了定量分析。计算模型和结果为工程实际中合成方案的选择和评估提供了参考。
The model of high-energy solid-state laser array synthesis was established and the coherent and non-coherent high-energy solid-state laser systems were analyzed and compared. The beam propagation factor (BPF) was introduced to evaluate the beam quality of the composite beam. The influence of turbulent atmosphere on the beam quality of the coherent and non-coherent composite slab lasers and fiber lasers was quantitatively analyzed. Computational models and results provide references for the selection and evaluation of synthetic schemes in engineering practice.
