Improving engine efficiency by extracting laser energy from hot exhaust gas RID A-1272-2007
(American Physical Society, 2003)
We show that it is possible to improve the efficiency of a classical Otto-cycle heat engine by adding a high-Q microwave cavity and a laser system that can extract coherent laser energy from thermally excited "exhaust" ...
Resonant enhancement of high-order optical nonlinearities based on atomic coherence RID A-1272-2007
(American Physical Society, 2002)
We show that the effect of coherent population trapping may result in resonant enhancement of chi((5)) or higher-order nonlinearities. The enhancement is accompanied by suppression of the other linear and nonlinear ...
