摘　　要：为了使 CO_2激光器在工业加工及军事上有更广泛的应用,采用铝合金拉制型材作为激光器壳体、盘装电感代替传统线绕电感的结构以及全金属封接工艺等,研制出一种紧凑型长寿命射频激励波导 CO_2激光器。可连续输出或在不高于20kHz 调制频率下脉冲输出,最大输出功率30W,实测工作寿命超过1500h,存储寿命超过1.5a。结果表明,这种激光器具有结构紧凑、输出功率稳定、工作寿命长、可连续及脉冲调制工作等特点,除了能满足各种材料的加工,也可在军事上应用。In order to have more comprehensive application in industry and military fields, a compact and long-life radio frequency（RF） excited waveguide CO2 laser was developed by means of Al-alloy laser housing, plat inductor coils instead of traditional rolling inductor, all-metal-sealed techniques and etc. The specifications of this laser are continuous or pulse output up to 20kHz modulating frequency,average laser output power up to 30W, over 1500h of working time and 1.5a of storage time. The results show that this laser has the characteristics of compact structure, steady output power, long life, continuous and pulse working-mode. It can be used both in industry and military fields.
