Multiple Increase in the Efficiency of Picosecond Stimulated Raman Scattering Excited by Bessel Laser Beams in Water

Stimulated Raman scattering of second harmonic picosecond pulses (60 ps, 532 nm) of an Nd 3+ :YAG laser in water when focusing a Bessel beam behind a conical concentrator with the displacement of the beam caustic through the free surface is studied. The generation of two Stokes (650 and 836 nm) and...
