Abstract
A new method for recording the phase structure of ultrashort optical pulses is proposed that makes no use of a reference pulse. Using three-wave inter actions in a nonlinear optical medium, a wave of spectral decomposition of an ultrashort pulse is transformed into a monochromatic wave. The spatial p hase structure of this wave contains information on the phase structure of the pulse spectrum and on the pulse form. This structure is analyzed by she aring interferometry.
