Abstract

Summary form only given. Methods for real time characterization of optical pulses based on time-lens operation have the advantage that they allow the direct measurement of the pulse intensity profile without any mathematical processing. In the present work we demonstrate the ability to measure both the intensity and the phase profiles of an optical pulse, using time-lens operation.The principle of the measurement can be explained by the known analogy between the diffractive propagation of light beams in the paraxial approximation and the propagation of narrow-band pulses in dispersive media.
