| 摘 要： | 为追求光泵气体THz激光器更高的输出功率和更好的光束质量，设计制作了金属网栅输出耦合镜，金属网栅输出耦合镜相比传统的小孔输出镜具有很多优势。详细描述了金属网栅输出耦合镜的结构，研究了金属网栅的理论模型。选择g/2a=76 ?m/20 ?m和g/2a=76 ?m/10 ?m这2组参数制作了金属网栅输出耦合镜，利用远红外傅里叶光谱仪对其THz波段的透过率进行测试，根据计算仿真得到结论：随着金属网栅线宽2a的增大，金属网栅的THz辐射透过率增大。

| Abstract: | In the pursuit of increased THz laser output power and higher beam quality, hybrid metal-mesh output coupler is designed and fabricated. The advantages of hybrid metal-mesh output coupler and its structure are described in this paper. The model of metal-mesh is studied to evaluate the transmittance. g/2a=76 ?m/20 ?m and g/2a=76 ?m/10 ?m are chosen to fabricate hybrid metal-mesh output coupler, and its THz transmittance is evaluated by Far Infrared Rays(FIR) Fourier transform spectroscopy. This study and former researches show that the transmittance of metal-mesh gets higher with the increase of 2a. |
