Abstract

Optical vortices carrying orbital angular momentum and with durations of femtoseconds recently have attracted great interest due to their potential applications in ultra-fast spectroscopy, high-intensity field physics and ultrafast optics through a new degree of freedom that they add to nonlinear optics.Thus, developing compact and efficient tools for their generation is required. Here, we present a reflective multi-material phase converter with high conversion efficiency over a broad wavelength range (over 200 nm) and high damage threshold that works directly with a Gaussian beam, common to most mode-locked lasers. Additionally the device allows to compensate dispersion previously acquired by the incident pulse. Spatio-spectro-temporal numerical simulations showing viability of the device are presented.
