“…Although the methods of generating such laser pulses, described, in particular, in ref. 26 are very preliminary and conceptual, one can be optimistic, as Atto-second laser science continues to demonstrate rapid progress and the necessary laser pulses can become feasible in very near future. The use of such a pulse could bring a numerous advantages to the fields of laser wake field acceleration or astrophysics.…”

This paper proposes a novel and effective method for generating GigaGauss level, solenoidal quasi-static magnetic fields in under-dense plasma using screw-shaped high intensity laser pulses. This method produces large solenoidal fields that move with the driving laser pulse and are collinear with the accelerated electrons. This is in contrast with already known techniques which rely on interactions with over-dense or solid targets and generates radial or toroidal magnetic field localized at the stationary target. The solenoidal field is quasi-stationary in the reference frame of the laser pulse and can be used for guiding electron beams. It can also provide synchrotron radiation beam emittance cooling for laser-plasma accelerated electron and positron beams, opening up novel opportunities for designs of the light sources, free electron lasers, and high energy colliders based on laser plasma acceleration.

“…Spatial chirp (spread of frequency components across the beam front; SC ) , pulse front tilt (inclination of the intensity front with respect to the propagation direction; PFT ) , angular dispersion (angular separation of light rays of differing frequencies; AD ) and wavefront rotation/Time vs. Angle (rotation of wavefront in time ‐ lighthouse effect ; WFR/TVA ) have all been discussed individually from a theoretical point of view and thorough experimental techniques have been developed to characterize them . Previous studies have clearly indicated that spatio‐temporal couplings can give rise to a strong directional dependence and more importantly anisotropic photosensitivity in isotropic homogeneous materials , which is thought to depend on the polarization orientation with respect to the azimuth of the PFT and is known as the blade effect .…”

“…However, a method called chirped-pulse amplification (CPA) clearly demonstrated that the manipulation of spectral components could be exploited for a benefit by providing a manner of alleviating the issue of damaging the gain rotation/Time vs. Angle (rotation of wavefront in timelighthouse effect; WFR/TVA) [22,23] have all been discussed individually from a theoretical point of view and thorough experimental techniques have been developed to characterize them [24].

Two hundred years after Malus' discovery of optical anisotropy, the study of polarization‐driven optical effects is as active as ever, generating interest in new phenomena and potential applications. However, in ultrafast optics, the influence of polarization is frequently overlooked being considered as either detrimental or negligible. Here we demonstrate that spatio‐temporal couplings, which are inherent for ultrafast laser systems with chirped‐pulse amplification, accumulate in multi‐pulse irradiation and lead to a strongly anisotropic light‐matter interaction. Our results identify angular dispersion in the focus as the origin for the polarization dependence in modification, yielding an increase in modification strength. With tight focusing (NA ≥ ∼0.4), this non‐paraxial effect leads to a manifestation of spatio‐temporal couplings in photo‐induced modification. We devise a practical way to control the polarization dependence and exploit it as a new degree of freedom in tailoring laser‐induced modification in transparent material. A near‐focus, non‐paraxial field structure analysis of an optical beam provides insight on the origin of the polarization dependent modification. However, single pulse non‐paraxial corrected calculations are not sufficient to explain the phenomena confirming the experimental observations and exemplifying the need for multi‐pulse analysis.

“…While it is possible to measure the spatial profile averaged over time and the temporal profile averaged over space, ultrafast lasers unfortunately suffer from an abundance of spatiotemporal couplings or distortions in which a pulse's temporal and spectral intensity and phase vary with transverse position, or equivalently, the spatial intensity and phase vary with time or frequency [1]. Some spatiotemporal couplings are useful in such applications as attosecond pulse generation, spacetime focusing, pulse compression, and nonlinear optics [2][3][4][5][6][7], but most are not. For example, in Kerr-lens mode-locked lasers, the output mode size depends on frequency [8], and, even if it does not, it necessarily will at a focus due to the wavelength dependence of a focal spot size for a given input spot size.…”

Complete characterization of a spatiotemporally complex pulse by an improved single-frame pulse-measurement technique

We further develop a simple device, called Spatially and Temporally Resolved Intensity and Phase Evaluation Device: Full Information from a Single Hologram (STRIPED FISH), for measuring the complete spatiotemporal intensity and phase, Ix; y; t and ϕx; y; t, respectively, of an arbitrary ultrashort pulse on a single camera frame (and hence, on a single shot). We have increased the measurable bandwidth, eliminated most aberrations, and improved the uniformity of the multiple holograms in the device. We demonstrate these improvements by making single-camera-frame measurements of spatiotemporally complex subpicosecond crossed and chirped pulses from a Ti:sapphire oscillator. In order to display the massive resulting data files-pairs of four-dimensional intensityand-phase data-we also develop a method for generating intuitive movies of the measured pulses. With these improvements, this device and its resulting movies should be able to perform and intuitively display true singleshot spatiotemporal measurements of most current ultrashort pulses.
