Transient non-linear optics of diamond under ultrashort excitation pulses

Abstract: Electronic response of crystalline diamond as well as high harmonic generation following irradiation by a single-cycle highintensity laser pulse was calculated through modeling the dynamics in the framework of the time-dependent density functional theory. The frequencies of the applied laser pulses vary over visible regime with a timescale shorter than typical quantum dephasing. High harmonic yields, show substantial deviation from what is obtained from the power scaling law of perfect solids under longer cycl… Show more

“…In this formalism, it is possible to follow the dynamics of the electronic distribution under a time-dependent electromagnetic field of tunable intensity, shape, duration, and frequency, that evolves together with the excited system over a certain time window. This method has been successfully applied to disclose the response to coherent radiation of bulk crystals [13][14][15][16][17], molecules [18][19][20][21][22], as well as organic, inorganic, and hybrid interfaces [23][24][25][26][27][28]. A recent development based on RT-TDDFT enables the fully ab initio simulation of two-dimensional electronic spectroscopy [29].…”
