Abstract:
An anomalously strong (up to 13 times) reduction of the threshold of the stimulated Raman scattering of 15-ps laser pulses in liquid nitrogen has been found when moving the caustic of a pump beam from the bulk through the free surface. A nonmonotonic N-shaped dependence of the stimulated Raman scattering threshold on the distance of the beam waist to the surface has been recorded for the first time with a minimum reached when the plane front of the beam caustic coincides with the surface. The physical mechanism of the detected phenomenon has been discussed.
