摘要 采用带有标准具的Fox-Smith谐振腔产生了稳定可调谐的单纵模TEA CO2激光输出。对干涉腔反射率的数值模型进行了研究,讨论了失谐角、子腔的匹配等因素对模式选择的影响,并且进行了实验验证。实现了10.6μm单纵模激光输出,能量140 mJ,重复率达到90%,腔内元件没有受到损伤。 We obtain a stable tunable single-longitudinal-mode （SLM） TEA CO2 laser oscillation by using a Fox-Smith cavity with a Fabry-P6rot etalon inserted in the sub-cavity. A numerical model of the refiectivity of the interference cavity is studied. The influence of the detuned angle and the sub-cavity-matching on the mode-choosing is discussed, and the verification experiment is carried out. Finally we get 140 mJ of SLM output energy at 10. 6 μm with repetition frequency of single longitudinal mode as high as 90%, and there is no damage on the elements in the cavity.
