| Abstract(in English) | A diffractive optics generates a large wavelength dispersion for a femtosecond laser pulse that has large spectrum bandwidth. An expansion of the pulse width and a reduction of the peak intensity generate on the focus position. To reduce the wavelength dispersion of a femtosecond laser pulse for the diffractive optics, we propose a technique of simultaneous spatial and temporal focusing with a diffractive lens. The optical scheme is performed by a dispersed irradiation of a femtosecod laser pulse with a grating to a diffractive lens with spatially different design wavelength. |
