Popis: | The possibility of increasing the efficiency of one-cascade 1.5-μm SRS lasing in a BaWO4 crystal placed into an external SRS cavity and pumped by a nanosecond Nd:YAG laser at a wavelength of 1.34 μm is studied. Conditions that prevent energy outflow to the second Stokes SRS component with a wavelength of 1.78 μm are found, which allowed us to increase the efficiency of one-cascade intracavity SRS lasing at 1.53 μm up to 60% and the slope efficiency up to the quantum limit (~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-μm SRS radiation energy to 40 mJ in a three-pulse train. |
