The intense stimulated emission, so-called superradiant radiation, can easily be observed in the case of a high gain laser amplifier such as the Xenon 3.5μm transition. The small signal gain of the 3.5μm transitions (5d3 3 − 6p22) is of the order of 4 db/cm and is one of the highest gains among known gas lasers[1], The intensity of amplified spontaneous emission can be comparable to that of ordinary cw gas laser. There are essential differences between the superradiant radiation and cw gas laser radiation; the spectral line-width of superradiant radiation is much broader than that of a cw laser. The center frequency of the superradiant radiation is more stable than in the case of usual cw laser, because no optical resonator is involved and the center frequency is determined by the energy levels of excited atoms[2,3].
