Abstract

The expected energetic performances are presented for amplification of short pulses (approximately 10^-12 s) either directly in chain pulsed chemical laser (PCL) active medium, or in active media created by optical pumping of resonantly absorbing molecules by radiation of PCL. The calculations were based on the data for PCL energetic and amplifying performances and also on the data for pumping of N₂O molecules by HF laser radiation, both being obtained by us earlier. For amplifying a short pulse in DF-CO₂ PCL active medium, the energy output of 6J/l is achievable, while 8 - 10 J/l is attainable for regenerative amplification in HF(DF) laser (50 J/l(DOT)atm - under free oscillation conditions for both). For regime of optical pumping, the energy of N₂O short-pulse radiation can make 10% of pump (PCL output) energy. A series of other promising three- and four-atomic molecules is considered. The comparison of various variants of embodying of superpowerful laser systems based of chain chemical lasers is carried out. The conception of construction of short- pulsed laser systems with radiation energy of up to 10⁴ J is submitted with the expectation of their using for creation of dense relativistic plasma, as new perspective object of researches, and for realization of laser fusion.
