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.

Since their introduction several decades ago, ultrashort laser pulses have allowed researchers to make the most temporally precise and accurate measurements ever made
The single-pulse measurement problem was solved by the introduction of frequency-resolved optical gating (FROG), a self-referenced technique that completely
An iterative generalized-projections reconstruction method is employed to determine the electric field of the attosecond-pulse. This approach has been modified to obtain the fs probe pulse, in effect evolving into a Blind FROG technique
Summary
Since their introduction several decades ago, ultrashort laser pulses have allowed researchers to make the most temporally precise and accurate measurements ever made Such measurements depend heavily on the ability to measure the pulses involved, and pulse-measurement techniques have traditionally lagged well behind pulse-generation techniques. This is because the measurement of an event has generally required the use of a shorter one, and ultrashort laser pulses are the shortest events ever generated. The single-pulse measurement problem was solved by the introduction of frequency-resolved optical gating (FROG), a self-referenced technique that completely. Several articles have reviewed the commonly used single-pulse measurement techniques [27,28,29,30], so we will focus on the two-pulse measurement problem and review the aforementioned techniques
