Copper vapor laser pumped by pulse-periodic high-frequency discharge

Dependence of induction copper vapor laser radiation on the parameters of RF discharge and the optical cavity

“…It is likely that with further optimization of the specified parameters, it would be possible to obtain a complete decomposition of W las into five separate pulses. We obtained an analogous effect (decomposition of a single pulse into two separate pulses) in a numerical experiment [4,8] at lower frequencies of RF current oscillations (f tr = 9.8 MHz and f = 10 kHz). Moreover, we also demonstrated the possibility of controlling the amplitude of these pulses by varying the voltage U(0).…”

“…In recent years, by using numerical methods, we substantiated the possibility of creating an electrodeless construction of a copper vapor laser (CVL) excited by a new method, namely, by a pulse-periodic induction discharge [1][2][3][4] aimed to significantly improve the operation characteristics. It was assumed that the absence of electrodes would simplify the construction, make the sealed-off active elements of this laser cheaper, and, to a certain degree, make their service period longer.…”

“…A physical model of an ICVL was thoroughly described in our works [1][2][3][4][5][6][7][8]. In addition to the equations describing the dynamics of non-equilibrium plasma parameters, it comprises the equations for the intensity evolution of induced laser radiation (spectral density) inside a cavity.…”
