通过串联使用激光器和微波激射器，有可能在热机的热废气中获得激光作用。这种“量子加力燃烧室”涉及工作分子的内部量子态以及腔量子电动力学的技术，因此属于量子热力学的范畴。结果表明，奥托循环发动机的性能可以提高到“理想”奥托热机的水平。此外，本工作还证明了一种新的无初始反转激光。
By using a laser and maser in tandem, it is possible to obtain laser action in the hot exhaust gases of a heat engine. Such a "quantum afterburner" involves the internal quantum states of the working molecules as well as the techniques of cavity quantum electrodynamics and is therefore in the domain of quantum thermodynamics. It is shown that Otto cycle engine performance can be improved beyond that of the "ideal" Otto heat engine. Furthermore, the present work demonstrates a new kind of lasing without initial inversion.
