Abstract
Dicke superradiance, that is, cooperative spontaneous
emission, has been observed in methyl fluoride, which is optically pumped by a pulsed carbon dioxide TEA laser operated on the P(20) line at 9.55 ~m. The far-infrared (FIR) super-radiant pulses, at a wavelength of 496 microns, were identified by the pressure (p) dependence of their widths and delays (inversely proportional to p) and their intensities
(as p2). These pulses were observed by a fast, sensitive Si:P photoconductor calibrated to give absolute intensity, and were recorded for a range of pressures from .44 to .01 torr in each of several sample lengths from 168 to 1021 cm. This was done for
