We demonstrate frequency-resolved optical gating (FROG) using cascaded second-order
nonlinearities (up-conversion followed by down-conversion). We describe two different …

In this paper, we conceptually propose and numerically demonstrate the generation of
ultrafast tunable super-oscillation (SO) light fields by tightly focusing a radially polarized …

We introduce a new approach to transient absorption spectroscopy based on measurement
at specific excitation intensities. A combination of datasets isolates individual perturbative …

I propose a superoscillation measurement method for subdiffraction incoherent optical
sources, with potential applications in astronomy, remote sensing, fluorescence microscopy …

The detection of rapid dynamics in diverse physical systems is traditionally very difficult and
strongly dominated by several noise contributions. Laser mode-locking, electron bunches in …

Several methods are now available for single-shot measurement of the complex field
(amplitude and phase profiles) of optical waveforms with resolutions down to the sub …

Four-wave mixing processes are ubiquitous in ultrafast optics and the determination of the
coefficients of the $\chi^{(3)} $ tensor is thus essential. We introduce a novel time-resolved …

Noise-induced excitability is a prevalent feature in many nonlinear dynamical systems. The
optically injected semiconductor laser is one of the simplest such systems and is readily …

We simulate multishot intensity-and-phase measurements of unstable trains of complex
ultrashort pulses using second-harmonic-generation (SHG) frequency-resolved optical …

The need to measure high repetition rate ultrafast processes cuts across multiple areas of
science. The last decade has seen tremendous advances in the development and …
