Abstract: Potential applications of ultrashort vortex pulses (ultrashort pulses with helical wavefronts) require compact tools to compensate for dispersion during their generation and propagation. In this work, a global simulated-annealing optimization algorithm, based on analysis of… read more here.

Abstract: We propose to obtain relativistic near-single-cycle optical vortices carrying orbital angular momentum through the post-compression of Laguerre-Gaussian pulses in gas-filled multipass cells. Our simulations revealed that 30 fs optical vortex pulses centered around 800 nm… read more here.

Abstract: We report the generation of high peak power linearly polarized femtosecond optical vortex pulses based on parabolic pulse amplification within a large-mode-area few-mode Yb-doped fiber (YDF) amplifier system. A dispersion-managed passively mode-locked Yb-doped fiber oscillator… read more here.
