摘要：

We demonstrate that, for tilted pulses, the contribution to group velocity that is due to spatial walk-off can compensate for the group-velocity mismatch in three-wave interactions. With 100-fs, 0.4-mu m pump pulses in P-barium berate, we obtained efficient parametric generation of collinear superfluorescence tunable in the range from 0.456 to 3.25 mu m.
