Single-shot phase-matching free ultrashort pulse characterization based on transient absorption in solids

Abstract: The frequency-resolved optical switching (FROSt) method developed for ultrashort pulse characterization is implemented for single-shot measurements. In this basic demonstration, the delay axis of the spectrogram is spatially encoded by the pump beam having a small incident angle with the photoexcited material. We present the calibration procedure for spectrograms acquired in single-shot and the temporal characterization of 44 fs pulses with central wavelength at 800 nm both in scanning and single-shot FROSt co… Show more

“…Many self-referenced techniques, with varying experimental complexity and limitations, aiming at characterizing ultrashort laser pulses, have thus been developed [1][2][3][4][5][6][7]. Recently, a phase-matching free pulse characterization technique exploiting transient absorption in solids as an ultrafast optical switch has been developed [8,9]. Briefly, this frequency-resolved optical switching technique (FROSt) consists in measuring the spectrum of a probe that propagates through a transparent dielectric medium.…”
