A 2D numerical model for the interaction of a femtosecond (fs) probe pulse with a Raman medium excited by two nanosecond (ns) laser pulses is presented. As such, numerical results show that by optimizing the tilt angle between the two driving pulses and the interaction length, the power of the probe pulse can be converted either into a quasicontinuous broadband spectrum or into a single high-order sideband. Moreover, the use of solid hydrogen with high-molecular density and small interaction length which allows a good overlap of tilted laser beams is an essential point of the technique.
