Abstract
We show that the parametric superfluorescence generated by a 200-fs pulse at 0.6 \ensuremath{\mu}m in a \ensuremath{\beta}-barium borate crystal occurs in directions, and at wavelengths, that minimize the group-velocity mismatch between pump and generated pulses. Favorable conditions for generation of tunable femtosecond pulses are found in noncollinear phase matching, a geometry of interaction which is worth exploiting in parametric devices.
