“…In the paper [11], energy transfer from intense laser pulses to a dielectric medium was calculated using time-dependent density functional theory. In the paper [12] the interaction of atto-and femtosecond pulses with diamond was described using the SALMON computer code [13].…”

“…It should be noted that in papers [10,11], nonlinear effects in the interaction of electromagnetic pulse (EMP) with matter were taken into account, but the influence of the effects of propagation and reflection of EMP as a result of interaction with the medium was not considered. In article [12], interaction with a thin sample of the medium was considered without any analytical description, only within the framework of numerical calculation.…”

The absorption of short laser pulses in an optically dense medium is theoretically studied based on the total absorption coefficient over the entire duration of the pulse, taking into account the effects of propagation and reflection of pulse from vacuum/medium interface. The approach is the generalization of our previous work [1], which traced a “bridge” between the micro- and macro-description of radiation processes in a medium induced by electromagnetic pulses of arbitrary duration. The expression for the total absorption coefficient is obtained in terms the complex refractive index of the medium. Various limits of this expression are considered. Numerical calculations of the dependence of the total absorption coefficient on the parameters of the laser pulses and the thickness of the medium layer were carried out and the results obtained were discussed.

“…Interaction of ultrashort electromagnetic pulses (USPs) with matter is a 'hot topic' of recent research [1][2][3]. This is largely due to the great success in the development of methods for generating USP with specified parameters (duration, envelope shape, amplitude) in a wide spectral range [4][5][6][7].…”

“…An important class of such pulses is wavelets which are the pulses without a carrier frequency. Wavelets form a complete set of functions with which the temporal shape of few-and subcycle pulses can be modeled [2].…”

The excitation of a quantum oscillator at transitions between stationary states by wavelet pulses with zero and nonzero area as a function of their duration and amplitude is studied. The excitation from the ground state is examined in detail, together with the specific features of this process during excitation from excited states. Analytical expressions for the main characteristics of excitation probability under weak and strong perturbation of quantum oscillator were obtained within limits of strict consideration. Particularly, it was found that, on a qualitative and quantitative level, there is no difference between excitation by pulses with zero and non-zero area.
