Wavelength Scale All-Optical Magnetization Control in Ferromagnetic Films
We report the first demonstration of tightly focused femtosecond (fs) circularly polarized Bessel-Gauss beams for wavelength-scale magnetization switching in Pt/Co films. When compared to traditional Gaussian beams, these beams show better focusing and energy efficiency.
