Few-cycle vortex beam generated from self-compression of midinfrared femtosecond vortices in thin plates

We demonstrate theoretically that a few-cycle vortex beam with high peak power can be generated by self-compression of midinfrared femtosecond in thin fused silica plates. first investigate the requirements solitonlike pulse on laser wavelength and parameters plates based three preconditions sufficient spectral broadening, appropriate dispersion compensation, inhibition multiple filamentation. Our simulations confirm existence regime 3-$\ensuremath{\mu}\mathrm{m}$ an input duration 90 fs compressed to 15.1 characteristics preserved. The conversion efficiency is as 91.5%, reaches 0.18 TW. work instructive for experiments generating high-peak-power beams will help obtaining isolated attosecond light vortices, opening alternative perspective ultrafast science.
