Abstract

We develop a method to pre-characterize a chirped pulse in single-shot supercontinuum spectral interferometry (SSSI). In this method, the spectral phase of both modulated (probe) and unmodulated (reference) pulses can be determined simultaneously.

Simplified single-shot supercontinuum spectral interferometry

Dhruvit Patel, Dogeun Jang, Scott W. Hancock +2 more

We have experimentally demonstrated a simplified method for performing single-shot supercontinuum spectral interferometry (SSSI) that does not require pre-characterization of the probe pulse. The method, originally proposed by D. T. Vu, D. Jang, and K. Y. Kim, uses a genetic algorithm (GA) and as few as two time-delayed pump-probe shots to retrieve the pump-induced phase shift on the probe [Opt. Express26, 20572 (2018)]. We show that the GA is able to successfully retrieve the transient modulations on the probe, and that the error in the retrieved modulation decreases dramatically with the number of shots used. In addition, we propose and demonstrate a practical method that allows SSSI to be done with a single pump-probe shot (again, without the need for pre-characterization of the probe). This simplified method can prove to be immensely useful when performing SSSI with a low-repetition-rate laser source.

We perform joint spectral intensity measurements by studying stimulated four wave mixing in a birefringent fiber photon pair source. Seeding the process with a chirped supercontinuum beam, measurements are acquired in as little as 5 s.

Single-shot Measurement of the Complete Temporal Intensity and Phase of Supercontinuum

We demonstrate the first technique for the complete temporal measurement of a single supercontinuum pulse. We achieve large ranges and high resolutions using polarization gating, a tilted gate pulse, and the cancellation of geometrical smearing.

Frequency-time and time-space mappings with broadband and supercontinuum chirped pulses in coherent wave mixing and pump-probe

Lomonosov Moscow

Broadband and supercontinuum pulses with a lin- ear chirp define a linear transform, mapping the difference between the instantaneous frequencies of pump pulses onto the delay time between these pulses. This delay between the pump pulses can be then mapped onto the spatial coordinate with the use of a broad-beam wave-mixing or pump-probe geometry. The new possibilities offered by these mappings for four-wave-mixing techniques are discussed. The spectral and temporal resolution of chirped-pulse wave-mixing and pump- probe techniques are examined. Single-shot multidimensional wave-mixing techniques using broadband and supercontinuum chirped pulses are discussed.
