In this study, the extended Overnight Index Rate (OIR) model is presented. The fitting function for the probability distribution of the OIR daily returns is based on three different Gaussian distributions which provide modelling of the narrow central

This paper presents results of the numerical modeling of a passively Q-switched intracavity harmonic generator as a source for laser micromachining. The model is based on the system of coupled rate equations for the active laser medium, passive Q-swi

This paper is focused on the systematic computer-based numerical research of processes taking place during laser/matter interaction on the nanosecond time scale. Special attention is paid to the dynamics of a laser with passive Q-switch and intra-cav

We demonstrate an eye-safe KTP-based optical parametric oscillator (OPO) driven intracavity by a diode-pumped 1064-nm Nd:YAG laser, passively Q-switched by a Cr4+:YAG crystal. The characteristics of this system, which operates at 1570 nm with a repet

We present a numerical model of the laser system for generating a special shape of the pulse: a steep peak at the beginning followed by a long pulse tail. Laser pulses of this nature are required for various applications (laser material processing, o
