The possibility of increasing the efficiency of one-cascade 1.5-{mu}m SRS lasing in a BaWO{sub 4} crystal placed into an external SRS cavity and pumped by a nanosecond Nd:YAG laser at a wavelength of 1.34 {mu}m is studied. Conditions that prevent energy outflow to the second Stokes SRS component with a wavelength of 1.78 {mu}m are found, which allowed us to increase the efficiency of one-cascade intracavity SRS lasing at 1.53 {mu}m up to 60% and the slope efficiency up to the quantum limit ({approx}80% at the SRS pulse energy up to 20 mJ). The use of pumping by laser pulse trains provided the possibility of increasing the 1.53-{mu}m SRS radiation energy to 40 mJ in a three-pulse train. (nonlinear optical phenomena)
