Investigation of lasing on Cd+, Zn+, Xe, and Ne transitions excited by a beam of nanosecond electrons

Simulation of NPL in experiments with e-beam pumping

“…1988;Gorjunov etal. 1989;Kushner 1989;Andreev et al 1992;Boichenko et al 1993;Sereda et al 1993;Karelin & Yakovlenko 1993;Karelin et al 1997) have revealed that the laser output parameters depend first on the pumping power and the rate of energy deposition into the active medium rather than on the pumping technique.…”

“…Thus, theoretical analysis (Gudzenko & Yakovlenko 1978;Kushner 1985;Bugaev et al 1988;Derzhiev etal. 1988b; Moratz et al 1988;Gorjunov etal.…”

“…The contribution from the cascade electrons is taken into account by doubling the ionization frequency. This approach (Gudzenko & Yakovlenko 1978) to the problems under consideration is advantageous in that there is no need to calculate an exact electron energy distribution function and therefore the required results can be obtained readily enough with reasonable accuracy.…”

“…Kinetic studies of the active media of high-pressure lasers pumped by electron beams and charged products of nuclear reactions (Gudzenko & Yakovlenko 1978;Bugaev et al 1988;Derzhiev ef aL1988b, 1990Moratz etal. 1988;Gorjunov etal.…”

“…This situation is also typical for the pumping by hard radiation photons-energetic electrons or ions-so-called "hard ionizers." In this approximation [hard ionizer approximation (Gudzenko & Yakovlenko 1978)], the energy distribution function for the plasma electrons can be considered as a Maxwellian function with the pumping source 8 if the ionization is accomplished by electrons. The contribution from the cascade electrons is taken into account by doubling the ionization frequency.…”
