Three-dimensional self-focusing of laser pulses in SBS-active media

Not Accessible

Your library or personal account may give you access

Abstract

The coupling between Kerr filamentation and stimulated Brillouin scattering (SBS) is numerically investigated for nanosecond laser pulses in silica. In self-focusing regime, phase-modulated broadband pumps may not weaken backscattering, which appropriate amplitude modulations can achieve.
