Abstract

Stimulated Raman scattering in high pressure molecular nitrogen is employed to convert the second harmonic (532 nm) output of a Q-switched (6-7 ns FWHM) Nd:YAG laser into ultraviolet, visible and near infrared laser light. Seven Raman lines, ranging from 355 nm – 847 nm are generated. Four of these lines through anti-Stokes Raman shifting (AS) while the remaining three, via Stokes Raman shifting (S). The spectra and temporal profiles of these Raman lines are studied at a 4.14 MPa N₂ pressure and 532 nm excitation energy of 1.75 J. All Raman components are observed to have sub-nanosecond pulse widths (FWHM) ranging from approximately 600 ps – 880 ps.
