title: Transient four-wave mixing with a collinear pump and probe.
abstract: We propose a new heterodyne scheme for performing time-resolved four-wave mixing experiments with collinear pump and probe beams. The method is not limited by phase-matching requirements and permits the investigation of thick samples and waveguide devices such as semiconductor optical amplifiers.
