Recent developments in experimental techniques for measuring two pulses simultaneously

Abstract

As many high-intensity ultrafast-optical measurements involve more than one pulse-typically one to excite a medium under study and another to probe it-a technique for measuring two pulses simultaneously is highly desirable. In two decades, two-pulse measurement techniques have advanced from ambiguity-laden to a recently developed technique that can measure a pulse pair with arbitrary central wavelengths, complexities and bandwidths. Here, we review recent efforts to simultaneously measure two ultrashort laser pulses using a single device.
