We show nonlinear propagation of a nondiffracting Bessel pulse. In regime of multiphoton absorption, it creates a 4 cm long channel of 3-photon fluorescence, i.e 80 times the equivalent Rayleigh range. © Optical Society of America.

Abstract
We show nonlinear propagation of a nondiffracting Bessel pulse. In regime of multiphoton absorption, it creates a 4 cm long channel of 3-photon fluorescence, i.e 80 times the equivalent Rayleigh range. © Optical Society of America.
