Abstract: (3066 Views)
In order to achieve a shorter attosecond pulse , we solved the time dependant 1D schrodinger equation for single Hydrogen atom. Applying the Fourier transformation to the dipole acceleration, we succeed to depict high order harmonics for a laser field with the first parameters. By superposing several harmonics in cut off vicinity, the isolated attosecond pulse is generated. Then we tried changing laser parameters, such as, varying the wavelength of the fundamental and the two controlling fields, using different pulse envelopes and at last, increasing the carrier-envelope phase, in order to achieve a shorter pulse.
Keywords: Carrier-envelope phase, cut off, Fundamental and controlling fields, Isolated attosecond pulse
