In this paper, we examine the factors minimizing the transient spikes in the evolution of a laser pulse. Our study is based on a mathematical model simulation of the laser implemented in Matlab Simulink. A model of the flash lamp excitation circuit i

Let us consider the family of symmetrical Laguerre-Gaus modes of zero azimuthal order which will be denoted as LG p0 . The latter is made up of central lobe surrounded by p concentric rings of light. The fundamental mode LG 00 is a Gaussian beam of w

Recent developments in laser materials, such as Nd/Cr:YAG ceramic with a broad absorption spectrum in the visible, have been applied to achieve highly-efficient and low-cost optical pumping by conventional sources. Our simulator based on the implemen

Modulated 532 nm laser pulses were generated by a Nd:YVO 4 microchip laser and a KTP crystal end-pumped by a 808 nm laser diode. The interest in such works arise from the efficiency of this type of laser in several applications. To obtain the desired

We propose a new method for the determination of the pumping coefficient dependence upon the variation of the flashlamp opacity in a pulsed Nd:YAG laser oscillator which cannot be determined by existing methods. The method that we propose is based on

The thermodynamics and kinetics of the diethylbenzene-benzene transalkylation have been studied in liquid phase over faujasite Y in a batch reactor. The reactions were conducted at several temperatures between 423 and 513 K. The main product of the r

The simmer circuit in the flash lamp-pumped solid-state lasers allows maintaining a low DC current in the lamp. Otherwise, the use of the high trigger voltage would be necessary. This considerably reduces the flash lifetime. With the simmer, just a s

The power supply of flash lamp‐pumped solid‐state lasers (such as ND: YAG Laser) basically consists of a trigger circuit, a simmer circuit and the main discharge circuit. All of which are synchronized by a command circuit. To reduce both size and
