Diffractive spatiotemporal lens with wavelength dispersion compensation.
A spatiotemporal diffractive lens composed of a chirped diffractive lens and a diffraction grating is proposed. The spatiotemporal diffractive lens gives an ultrashort laser pulse with minimal duration only at the focal point. It also compensates for wavelength dispersion generated not only in the diffraction lens itself but also in other optical components in the experimental setup.
