Tunable-shift stimulated Raman scattering in water by chirped 50 fs to 4.5 ps UV-pulses
Forward stimulated Raman scattering (SRS) induced by focused 400 nm pulses chirped to different pulse durations is observed in water and heavy water. The first Stokes Raman peak shift is shown to be tunable in the range of 3500 − 4200 c m − 1 in water and 2450 − 3250 c m − 1 in heavy water. It is de...
