Influence of the excitation circuits on the CuBr laser performance

Determination of space-time resolved electron temperature in nanosecond pulsed longitudinal discharge in various noble gases and discharge tube constructions

“…The results obtained are in a fair agreement with the self-consistent models developed for NPLD in Ne-Cu and Ne-CuBr lasers [1,2], as well as to a certain extent with the time-resolved space-averaged electron temperature presented in figure 5, which was obtained by time-resolved measurement of the electrical discharge parameters, such as tube voltage and discharge current [7]. …”

“…The temperature at the quartz tube surface is measured by a thermocouple. The investigated NPLDs are excited by an electrical scheme with interacting circuits (IC scheme) described in detail in [2].…”

“…It is very important for gas-discharge laser physics, gaseous discharges, plasma technologies, gas-discharge mass spectroscopy, absorption and emission spectroscopy and plasma in general. The electron temperature determines thoroughly the characteristic constants for elastic and inelastic electron-atom and electron-ion collisions, as well as the three-body electron-ion recombination [1,2]. In particular for gas discharge lasers, the electron temperature directly influences the formation of the population inversion with the abovementioned processes or indirectly through heavy particles' interaction, such as asymmetric charge transfer, Penning ionization, etc.…”

The effect of an axial external magnetic field on the output power of a small-bore CuBr laser

“…This advantage yields a significantly shorter warm-up time for the halide laser, which is important to reduce downtime in commercial applications [1][2][3][4][5][6][7]. Numerous experimental investigations have been performed to increase the efficiency and average output power of CVL [8][9][10]. One of the intended methods to obtain high power is employing a largebore tube.…”

CuBr vapor laser with a central electrode

“…The laser cavity consists of two flat mirrors: a 99.8 % reflectivity mirror and a plane-parallel c quartz output coupler. 6 The CuBr vapor laser with CE is IC-excited (the interacting circuits IC excitation of the Cu.Br laser is described in details in previous papers 56) The electrical scheme for the IC -laser excitation is shown in Fig. 1 Initially, some experiments to determine the best excitation circuit configuration were carried out.…”
