Abstract
Light pulses in the femtosecond range require sophisticated methods for their precise temporal characterization. Several techniques have been developed over the past decades that deliver the temporal structure of ultrashort light pulses. Still, there are special cases left that cannot be treated directly by established methods. Here we expand the applicability of existing tools to the case of non-collinear propagation of a pair of identical pulses with an unknown, but fixed temporal spacing. By applying the successful dispersion scan (d-scan) technique to a setup known from the established frequency-resolved optical gating (FROG) technique, we record a rather peculiar measurement trace. A nonlinear signal is only generated outside optimal temporal compression, in contrast to previously used techniques. This feature enables an improved dynamic range for the measurement of the temporal wings of a pulse. We expand a well-established retrieval algorithm to reconstruct the pulse structure from the measurement data. Our results are confirmed by comparison to d-scan and FROG measurements.
