Abstract
We investigate femtosecond stimulated Raman scattering (SRS) in H-2, D-2, H D, and CH4 excited with 300-fs-duration pulses at 390-nm wavelength and wit h as much as 0.1 mJ of energy. We show that the SRS-generation threshold an d conversion efficiency are due to the transient nature of SRS in femtoseco nd regime. We determine optimal conditions for efficient generation in the broad spectral range 289-797 nm and show how self-phase modulation and whit e-light generation Limit the ultimate conversion efficiency.
