Abstract

Recently, Jaroszynski and King found superradiance(SR) occurring in photodissociatively created systems using NaI and n-C3F7I molecules, and Hahn and Lee have performed the amplified spontaneous emission(ASE) experiment in an iodine photodissociation laser(IPL) amplifier. In general, to observe SR experimentally, a very short intense pumping pulse of which FWHM is about a few tens of nanoseconds, is used for making a totally inverted system. But in this work, the amplifier is pumped with conventional flashlamps of FWHM=3us, yet we have detected a output pulse which is a superposition of ASE and SR. The temporal behaviour of the pulse is investigated in detail, and the experimental results are compared with theoretical results.
