Abstract:
We investigate the upconversion process of broadband incoherent light generated by parametric downconversion.
We focus on the incoherent component of the sum-frequency generated (SFG) radiation, analyzing its
spatiotemporal properties. We show that its spectrum has a skewed geometry in space-time, originating from
a compensation between the group-velocity mismatch and the spatial walk-off of the fundamental and the
SFG fields. The results are illustrated by a theoretical modeling of the optical system and by experimental
measurements. © 2014 Optical Society of America
