摘要
Conical continuum Stokes and anti-Stokes emissions are observed when intense 100-fs/620-nm ultrafast laser pulses propagate through an ethylene glycol medium. The angle of the anti-Stokes conical emission is modeled by class-II Raman and four-photon parametric generations in a small-scale filament with a nonlinear index change.
