Model of a nuclear – optically – pumped liquid laser

The model of a nuclear – optically – pumped liquid laser is constructed and the laser characteristics are analysed for different parameters of the setup and pump pulse, compositions of the converter media and active elements. The lasing parameters of the liquid laser using heavy-water solution of ²⁴⁵Cm as the converter medium and neodymium-containing phosphorous oxychloride (phosphoryl chloride) as the active element are calculated. It follows from the results of calculations that lasing can be achieved in these media pumped by neutrons from the BARS-6 reactor.
