Episode Synopsis "ECE 616 Student Presentation: MIIPS - Pulse-Shaper Enabled Pulse Measurement and Shaping"

Common ultrafast laser pulse characterization methods, such as autocorrelation, frequency-resolved optical gating (FROG), and spectral phase interferometry for direct electric-field reconstruction (SPIDER), can only measure the pulse characteristics, whose use is limited when measuring and shaping the pulse are both required. As a pulse-shaper-assisted measurement method, multiphoton intrapulse interference phase scan (MIIPS) can simultaneously characterize the pulse and shape it into specified forms. In MIIPS, a pulse shaper imposes a known reference spectral phase function to the pulse to locally cancel distortions caused by the spectral phase to be determined. The effect of the introduced phase function is monitored through measuring the spectrum of a nonlinear signal of the pulse. When the desired cancellation is achieved, the unknown spectral phase function can be deduced from the reference function. In this study, the theory of MIIPS is analyzed and the experimental realization is discussed.
