摘要:

We demonstrate a new technique for displaying the electric field autocorrelation function of a laser pulse in real time, using two‐beam coupling in a photorefractive crystal. This technique does not require phasematching, is simple to align, and can be used over the entire visible and near‐infrared regions of the spectrum, even with weak laser beams.
