“…[6][7][8][9] 4). Since all calculation methods of the rate constants of electron mixing have a great error (up to 100 % and above) and the buffer mixing of Xe(5d) states constant information is absent the main stage of simulation consisted in variation of rate constants in region of errors of their calculation according to best agreement with experimental data.…”

The data on optimization of output parameters (output energy and laser efficiency) and distribution of laser radiation energy on the output window cross-section of the wide-aperture Xe-laser pumped by a radially-convergent e-beam with pulse duration of 0,5 s at the FWH1VI were obtained. It is shown experimentally, that the requirement of homogeneity of output laser radiation across the aperture limits the energy deposition value from below, and the requirement of maximal laser efficiency restricts the energy deposition value from above.In the experiment the maximal laser efficiency as 1,5-2 % was obtained at the specific energy deposition of 12-14 inJ/cm3atm. The calculations show that with cleaning of the operating mixture from molecular gases impurities the laser efficiency and energy output can be increased in 1 . 5-2 times. The negative influence of impurity gases at optimum range of pumping power is decreasing of electron temperature and as a consequence decreasing of the upper laser level pumping.

“…Russian institutions also develop and create the powerful excimer lasers and laser systems [4][5][6][7][8][9][10][11][12]. In particular, a KrF laser system with a Garpun output unit (Institute of Physics, Russian Academy of Sciences) has an output aperture with a size of 16 × 18 cm and one generates radiation pulses with energy of 80 J and pulse duration of 100 ns [12].…”

“…The excimer lasers developed at the High-Current Electronics Institute (HCEI), Siberian Division, Russian Academy of Sciences, generate pulses with an energy of greater than 100 J [4][5][6][8][9][10][11]. The two most powerful XeCl lasers (308 nm) with apertures of 40 [8] and 60 cm [9][10][11] generate pulses with energies of 660 J and 1.9 kJ and pulse durations of about 350 and 250 ns, respectively.…”

Three high-power excimer laser systems with apertures of 25 and 40 cm of the output laser beam are described. The first and second laser systems consist of four and five excimer lasers, respectively. Third system consists of Ti:Sa front end and XeF(C-A) amplifier. The experimental results of the generation of the high-quality and high-power laser pulses are presented. Laser beams with pulse energy of up to 330 J (308 nm, 250 ns) and peak power 14 TW (450 nm, 50 fs) were obtained.

XeCl laser with an output energy 200 J

This paper discusses the mechanical effect of water on the deformation of silicon monocrystals under nano-indentation with the aid of molecular dynamics analysis. The rigid TIP4P model was used to simulate the interactions between water molecules while the long-ranged non-bonded Lennard-Jones potential was applied for the pairs of unlike molecules. It was found that upon loading water molecules are lodged into the cavities of the silicon substrate, causing subsurface damage. The diamond cubic structure in the indentation zone transforms into an amorphous state with a body-centred tetragonal form (β-silicon) below the indentor. The presence of water significantly reduces the indentor-silicon adhesion that alters the structure of the residual deformation zone after complete unloading.
