Simulation of high-energy nanosecond Raman laser on a $\mathrm{BaWO_4}$ crystal

The operability of a wide-aperture barium tungstate ($\mathrm{BaWO_4}$) crystal as an active medium of a nanosecond laser on forced Raman scattering with a record high energy of 1 Joule output radiation pulses is investigated. The experiments have shown the high resistance of the $\mathrm{BaWO_4}$ crystal to laser pulses with a laser destruction threshold of 10 J/cm2. Mathematical modeling of a Raman laser when pumped with a neodymium glass laser (1053 nm, 6 J) showed an effective conversion of pumping energy into Stokes components with energies of 1.8 (1167 nm), 1.7 (1214 nm) and 0.8 J (1265 nm) in an optical resonator, the output mirror of which is the output end of the Raman crystal.
