High harmonic generation from solids is an interesting and growing field of research. Here the authors explore HHG from GaSe sample driven by two-color fields and find that controlling electron trajectories in a band structure enable to modify the an

The generation of high-order harmonics from hybrid organic–inorganic perovskites (HOIPs) is demonstrated by the excitation with a strong mid-infrared laser pulse. We prepare three types of HOIP polycrystalline thin film samples by solution processe

Theoretical investigation is conducted of high-order harmonic generation (HHG) in silicon thin films to elucidate the effect of light propagation in reflected and transmitted waves. The first-principles simulations are performed of the process in whi

We investigate multi-channel dissociative ionization of ethanol in intense near-infrared laser fields with photoelectron-photoion coincidence three-dimensional momentum imaging. As the intensity of the linearly polarized laser field increases to 23 T

Numerical study of laser excitation in silicon helps in understanding the physical processes during excitation and the consequent onset of damage in the target. We present Three-Temperature model which considers the electron, hole and lattice tempera

Laser excitation in Silicon is studied using a new Three-Temperature model. The thresholds for partial melting and electron emission show good agreement with experimental results. Comparison with two-temperature model is also done.

Laser processing studies of semiconductors are crucial for the practical applications, as well as for understanding the physics of such interactions. Theoretical modeling of these interactions usually involves the use of Two-Temperature model (TTM),

We have studied the linear and nonlinear optical response of WSe2 monolayer by the classical Maxwell equations combined with TDKS equations to describe the propagation of electromagnetic fields in thin 2D layers. WSe2 monolayer is chosen because of s
