Computation of Atomic Dipole Spectra for Different Atoms by Considering Short and Long Electron Trajectories under the Intense Laser Pulse
Sayrac, Muhammed (9TH INTERNATIONAL ADVANCED TECHNOLOGIES SYMPOSIUM, 2021)In this work, computation of the nonlinear dipole response of a single atom is performed by considering the ionization of the electron under the intense laser field. The dipole spectra for xenon (Xe) and argon (Ar) gases ... -
Effect of Ultrashort Laser Pulse Shape on the Dipole Spectrum of a Single Electron
Sayrac, Muhammed (International Conference on Advances in Engineering, Architecture, Science and Technology (ICAEAST 2021)), 2021)In this study, the effects of ultrashort laser pulse shape for the laser-matter interaction have been considered. Three different pulse shapes, Gaussian, Super-Gaussian, and Cosine-Squared, are used to calculate the dipole ... -
Generation of Coherent Extreme Ultraviolet Radiation in an Air Gas Cell with a High Power Femtosecond Laser System
Sayrac, Muhammed (Springer, 2021)High harmonic generation (HHG) in air medium is experimentally produced by using a state-ofthe-art high power laser system. The harmonic orders up to 35th harmonic are well observed. Optical power dependence of harmonic ... -
Generation of even and odd harmonics in the XUV region with controlling the relative delay and polarization of two-color fields
Sayrac, Muhammed; Kolomenskii, Alexandre A.; Dong, Jian; Schuessler, Hans A. (Elsevier, 2021)We report high harmonic generation in the extreme ultraviolet (XUV) region by using two-color laser fields at the wavelengths of 800 nm and 400 nm. With a Ti: sapphire femtosecond laser at a 10 Hz repetition rate efficient ... -
