气体激光器的散热仅仅依靠扩散率是不够的。在这种情况下，平均功率输出太有限。通过在气体内产生流动并获得强制对流的好处，性能得到了改善。但是，如果流动可以用来提高功率输出，它也可以用来更进一步，产生激光作用所必需的条件，从而创造出气体动力学激光器。本文介绍了这种设备背后的理论，并描述了一个实验装置，证明了这一概念的优点。
It is not enough to depend upon diffusivity to dissipate the heat from a gas laser. Under the circumstances, average power outputs are too limited. By generating flow within the gas and deriving the benefits of forced convection, performance is improved. But if flow can be used to improve power outputs, it also can be used to advance a step further and generate the conditions that are necessary for lasing action-thereby creating a gasdynamic laser. This article covers the theory behind such a device and describes an experimental unit that has proved the merit of the concept.
