Streak camera investigation of the self-focusing onset in glass

The onset of self-focusing in a glass sample has been studied with a streak camera. After passing through the sample, the beam is no longer focused by a subsequent lens into a nearly diffraction-limited spot, but rather into a time-dependent ring. A simple model explains these results and indicates...

Description
Summary:The onset of self-focusing in a glass sample has been studied with a streak camera. After passing through the sample, the beam is no longer focused by a subsequent lens into a nearly diffraction-limited spot, but rather into a time-dependent ring. A simple model explains these results and indicates practical limitations for uniformly illuminating small targets with a Nd:glass laser chain.
