Cubic nonlinear effects: self-focusing and modulation instability in glasses



Theoretical and experimental study of optical propagation in Kerr glassy media with nonlinear losses as stabilizing mechanism for two-dimensional soliton-like beams and modulationally unstable patterns. We investigate picosecond pulse self-channeling and multiple filamentation in heavy metal oxide glasses (HMO) with ultrafast Kerr response and multiphoton absorption in the near infrared.
