Paper Abstract

A sequence of quasi-equally spaced spectral lines, ranging from the IR to the UV was obtained, when 1.06-micrometers linearly polarized pulses of duration 30 ps and energy of up to 40 mJ were focused into a cell filled with hydrogen at pressures of up to 120 atm and formed there is a self-focusing channel. The average frequency interval between spectral lines was approximately equal to the frequency of rotational transition in hydrogen 587 cm-1. These lines exhibited a substructure made up by components produced in hydrogen by stimulated rotational and vibrational Raman scattering and cascaded four-wave parametric processes. In the visible, the energy of each spectral line was around 10(mu) J.
