Optical Pumping and Ferrite Flash Discharges

State of and prospects for XeF(C−A) optically pumped lasers

“…A detailed description of the installation and experimental technique is given in [9]. The laser was powered by 5-kJ energy stored in a capacitor bank.…”

“…Thus, a device 0.5-1 m in length with an input energy of 1-5 kJ has become an object of experimental investigations. The first experiments with a compact laser demonstrated an efficiency of about 5 9 10 -5 [8,9]. Up to now, the reason for the low efficiency is not clear.…”

Arc discharge sliding over a conducting surface

“…Since the systems with a solid conductor are of the most practical interest for initiation of extended plasma formation, a sample of NiMn ferrite that demonstrated good characteristics in laser experiments [7] was used in our experiments with discharge initiation.…”

“…The method of initiation under consideration was further developed in [4][5][6][7]. It was suggested that a NiMn ferrite, which has an appreciable conductivity in the normal state, be used [4] as an initiating component.…”

“…The emission and gas-dynamics characteristics of discharge in the stage of initiation of a highcurrent pulsed arc were studied in [6]; there, a numerical algorithm was developed to solve the two-dimensional problem on dynamics of surface discharge with allowance for the energy transport by radiation, and the results of calculations were found to agree satisfactorily with experimental data. In [7], an initiating component of 90 cm in length was used in the design of a high-power radiation source for optical pumping of excimer lasers. The long-term (104-105 pulses) pulse-recurrent mode of arc initiation with energy supply of about ,,~ 104 kJ and tolerable erosion of the surface of the initiating component were demonstrated.…”
