Abstract
A simple theory shows that phase modulation on a pulse may be reversed in time (e.g., positive chirp to negative) by degenerate four‐wave mixing in an optically thin nonlinear medium. In thick media, the reflected pulse field is not truly time reversed, but is proportional to the time integral of the conjugate incident field.Keywords
