“…Proposed in 1998 by Iaconis and Wamsley [7,15], SPIDER and its many variants have been recognized as an exceptional tool for characterizing pulses [4,[13][14][15][16][17][18][19][20][21][22][23][24]. Its success is due to its intrinsically ultrafast [18] and single-shot [19] nature, as well as to its simple, direct and robust phase retrieval procedure [14,15].…”

“…The classical SPIDER derives the pump from the PUT [4,7,15], making the technique intrinsically self-referencing. Alternatively, the use of a well-characterized pump reference pulse can improve the accuracy and reliability of the method [20], and this approach is commonly named X-SPIDER [4,21,23]. Typical SPIDER and X-SPIDER methods are designed for the characterization of optical pulses shorter than 100fs [4] and peak powers exceeding 10kW, and hence are not ideally suited to telecommunications.…”

Abstract:Finding an optimal phase pattern in a multidimensional solution landscape becomes easier and faster if local optima are suppressed and contour lines are tailored towards closed convex patterns. Using wideband second harmonic generation as a coherent control test case, we show that a linear combination of spectral phase basis functions can result in such improvements and also in separable phase terms, each of which can be found independently. The improved shapes are attributed to a suppressed nonlinear shear, changing the relative orientation of contour lines. The first order approximation of the process shows a simple relation between input and output phase profiles, useful for pulse shaping at ultraviolet wavelengths.

“…The well-established methods of the past two decades, including FROG [11], SPIDER [12], MIIPS [13], and D-Scan [14], have played important roles in the development of ultrafast laser sources and for characterizing laser pulses used in a wide range of experiments. However, they suffer from a number of limitations in their capabilities: (i) they measure only the spectral/temporal intensity and dispersion/chirp, not the full electric field, including the carrier-envelope phase (CEP); (ii) they cannot measure the relative phase across spectral nulls without an auxiliary field with a bandwidth that spans the null [15,16]; (iii) for ultrabroad bandwidth pulses, the bandwidth and efficiency of the measurement is limited by the requirement to use a nonlinear material to act as a time-stationary filter; and (iv) the pulse is rarely measured in situ, which necessitates a careful calibration of the linear and nonlinear space-time propagation of the pulse from the diagnostic to the site of the experiment.…”

Advances in the generation of ultrashort laser pulses, and the emergence of new research areas such as attosecond science, nanoplasmonics, coherent control, and multidimensional spectroscopy, have led to the need for a new class of ultrafast metrology that can measure the electric field of complex optical waveforms spanning the ultraviolet to the infrared. Important examples of such waveforms are those produced by spectral control of ultrabroad bandwidth pulses, or by Fourier synthesis. These are typically tailored for specific purposes, such as to increase the photon energy and flux of high-harmonic radiation, or to control dynamical processes by steering electron dynamics on subcycle time scales. These applications demand a knowledge of the full temporal evolution of the field. Conventional pulse measurement techniques that provide estimates of the relative temporal or spectral phase are unsuited to measure such waveforms. Here we experimentally demonstrate a new, all-optical method for directly measuring the electric field of arbitrary ultrafast optical waveforms. Our method is based on high-harmonic generation (HHG) driven by a field that is the collinear superposition of the waveform to be measured with a stronger probe laser pulse. As the delay between the pulses is varied, we show that the field of the unknown waveform is mapped to energy shifts in the high-harmonic spectrum, allowing a direct, accurate, and rapid retrieval of the electric field with subcycle temporal resolution at the location of the HHG.Published by The Optical Society under the terms of the Creative Commons Attribution 4.0 License.
