Abstract

The short range of fission fragments causes a specific energy input inhomogeneities which, along with excited gas heat exchange with laser cell walls, leads to density spatial redistribution, i.e., to the violation of active medium optical homogeneity. As noted in paper [1], with a reference to the 1980 report of A. N. Sizov and Yu. N. Deryugin, numerical and theoretical investigations of the dynamics of optical inhomogeneity origination and development in nuclear pumping lasers first began at the VNIIEF. During phase one, these investigations only pertained to the phenomena occurring in sealed lasers excited by pulsed neutron fluxes. This important aspect of NPLs is discussed in this chapter.
