优化后的连续337微米激光器的增益和饱和强度随管径的变化呈反比。然后推导出波导激光器的功率作为几何参数、损耗和耦合的函数的表达式。为了优化耦合，功率是具有明确定义的最大值的管直径的强函数。最佳直径仅取决于管长和损耗。结果与测量功率的三个波导激光器提供30 mW，100 mW，和170 mW的放电1米，2米，和3米的长度。这种激光器与光泵亚毫米激光器相比具有竞争力。
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.
