“…Also, the gas-filled waveguide is in general implemented in a vacuum system which adds bulk and complexity to the setup. To overcome these disadvantages, we propose to use the newly developed technique based on multi-plate spectral broadening [34][35][36][37][38][39][40][41][42] . This technique uses several pieces of thin fused silica plates, each with a thickness of a few hundred of micrometers, placed after the focus of the fundamental laser beam to broaden the spectral of the input pulse through SPM while avoiding the breakdown and the spatial distortion in the medium due to self-focusing and conical diffraction [43,44] .…”

We report on compact and robust supercontinuum generation and post-compression using transmission of light through multiple thin solid plates at the SwissFEL x-ray free-electron laser facility. A single stage consisting of three thin plates followed by a chirped mirror compressor achieves compression of initially 30 fs pulses with 800 nm center wavelength to sub-10 fs duration. We also demonstrate a two-stage implementation to compress the pulses further to sub-5 fs duration. With the two-stage setup, the generated supercontinuum includes wavelengths ranging from 500 nm to 1100 nm. The multi-plate setup is compact, robust, and stable which makes it ideal for applications at free-electron laser facilities such as pump-probe experiments and laser-arrival timing tools.

“…In this paper, for the first time to our best knowledge, we demonstrate the generation of supercontinuum vortices from intense femtosecond vortex beam by using several thin fused silica plates. The thin-plate scheme has been successfully used to generate supercontinuum from femtosecond Gaussian beams [20][21][22]. Here we use the thin-plate setup to inhibit the breakup of the intense femtosecond vortex beams.…”

We demonstrate numerically and experimentally the generation of powerful supercontinuum vortices from femtosecond vortex beams by using multiple thin fused silica plates. The supercontinuum vortices are shown to preserve the vortex phase profile of the initial beam for spectral components ranging from 500 nm to 1200 nm. The transfer of the vortex phase profile results from the inhibition of multiple filamentation and the preservation of vortex ring with relatively uniform intensity distribution by means of the thin-plate scheme, where the supercontinuum is mainly generated from the self-phase modulation and self-steepening effects. Our scheme works for vortex beams with different topological charges, which provides a simple and effective method to generate supercontinuum vortices with high power.

“…and compensating the induced temporal chirp with chirped mirrors. Table 1 also gives several experimental results [22][23][24][25][26][27][28][29] , where CEP-stable sub-optical-cycle (1.2 fs) light pulses have been obtained 25 . Recently the concept of post-compression, previously demonstrated with low-energy ultra-fast lasers, has been extended to high-energy lasers by A. Zheltikov and G. Mourou et al in order to generate few-cycle, PW and even EW…”

The rapid development of the optical-cycle-level ultra-fast laser technologies may break through the bottleneck of the traditional ultra-intense laser [i.e., Petawatt (PW, 1015 W) laser currently] and enable the generation of even higher peak-power/intensity lasers. Herein, we simulate an ultra-broadband concept for the realization of an Exawatt-class (EW, 1018 W) high peak-power laser, where the wide-angle non-collinear optical parametric chirped-pulse amplification (WNOPCPA) is combined with the thin-plate post-compression. A frequency-chirped carrier-envelope-phase stable super-continuum laser is amplified to high-energy in WNOPCPA by pumping with two pump-beamlets and injected into the thin-plate post-compression to generate a sub-optical-cycle high-energy laser pulse. The numerical simulation shows this hybrid concept significantly enhances the gain bandwidth in the high-energy amplifier and the spectral broadening in the post-compression. By using this concept, a study of a prototype design of a 0.5 EW system is presented, and several key challenges are also examined.
