The gain and the saturation intensity of optimized cw 337-microm lasers are shown empirically to vary inversely as tube diameter. An expression is then derived for the power of a waveguide laser as a function of geometrical parameters, losses, and coupling. For optimized coupling the power is a strong function of tube diameter with a well defined maximum. Optimum diameter depends on tube length and losses only. The results agree well with the measured powers of three waveguide lasers delivering 30 mW, 100 mW, and 170 mW from discharges of 1-m, 2-m, and 3-m lengths. Such lasers are competitive with optically pumped submillimeter lasers.
实验表明，优化后的连续波337微米激光器的增益和饱和强度与管径成反比。然后推导出了波导激光器功率与几何参数、损耗和耦合之间的函数表达式。对于优化耦合，功率是管径的强函数，且有一个明确的最大值。最佳直径仅取决于管长和损耗。这些结果与三台波导激光器的测量功率非常吻合，这三台激光器分别从1米、2米和3米长的放电中输出30毫瓦、100毫瓦和170毫瓦。这种激光器与光泵浦亚毫米波激光器具有竞争力。
