Various ways to create a master radiator at wavelength 1.315 μm are considered, and its optimum construction layout is chosen, based on obtaining efficient emission of the second Stokes component in a stimulated-Raman-scattering solid-state laser. An analysis is given of active crystals, and two solid-state pairs are proposed: laser crystal Gd3Ga5O12:Nd+a crystal of KY(WO4)2, and laser crystal LaF3:Nd+a crystal of KGd(WO4)2. A version of the layout with reduced losses is considered, based on Stokes components with simultaneous suppression of parasitic inversion dumping at a neodymium transition in the 1.3-μm region. The laser signal is amplified in a preamplifier stage based on iodine vapor, the gain was 150, and an output energy up to 60 mJ is obtained.
