Laser characteristics of the OKUYaN pilot facility: а) – laser beam “signature” at the output from the amplifier of the “Stand B” reactor-laser system (l = 2.03 µm); b) – pumping power (1) and total power along the whole laser generation channel (Egen = 43 ±2 J; Espec > 1.5 J/l) on the 2.03-µm transition (2) in He-Ar-Xe medium; c) – pumping power (3) and total power along the whole laser generation channel (one LAEL; Egen = 0.7 ±0.1 J) on the 391.4-nm transition (4) in He-N2-H2 medium.
