Abstract

The dependence of single pass stimulated Raman scattering (SRS) in liquid water on temperature was investigated. Thermal self-defocusing and competition with backward stimulated Brillouin scattering were found to be the major limiting factors for forward SRS (FSRS) generation. Experiments were performed to show that water cooling reduces these factors, resulting in significant enhancement of the FSRS and leading to a maximum conversion efficiency of 35% for pump energy of 120mJ/pulse and for water at a temperature of 4°C. Computer simulations of the involved waves resulted in FSRS efficiencies agreeing well with the experimental ones.
