In this article, femtosecond pulses, especially designed by multicolor beam superposition
are used for high-order harmonic generation. To achieve this purpose, the spectral …

Generation of high-order harmonics (HOHs) and attosecond pulses in the barrier
suppression ionization regime for a target of hydrogen molecular ion, H _ 2^+ H 2+, with …

Using the metallic nano-antennas we can enhance the intensity of a laser pulse to prepare it
for high-order harmonic generation. Plasmonic resonances in the metal surfaces cause a …

Due to the numerous diseases caused by apoptosis, the existing methods for detecting early
apoptosis are not effective. To explore the effect of nanostructured biosensors on the …

We solved one dimensional Schrodinger equation in a H2+ molecular environment by using
3 femtosecond homogeneous and nonhomogeneous laser fields. In homogeneous case, we …

High-order harmonics intensity and subsequently attosecond pulses which are generated
after the interaction of some two color femtosecond pulses with helium ions are studied in …
