“…A Pyrex glass sleeve 80 mm OD × 1 mm wall was used to inhibit transient current flow between the HT electrode and the stainlesssteel chamber walls. The pulsed power supply, delivering ∼1 µs risetime, high-voltage pulses at kilohertz repetition frequencies, was a thyratron switched exciter circuit with three-stage magnetic pulse compression, previously used to drive a high-power copper vapour laser [28]. Sinusoidal (ac) voltage waveforms were generated by a signal generator and Acoustics Research AR700A RF power amplifier driving a 20 : 1 step-up transformer.…”

“…The relevant cross sections and rate constants were obtained from Refs. [10][11][12][13][14][15][16][17][18][19][20][21]. The simulation results were determined by a set of boundary parameters including the geometrical dimension of the discharge tube, the parameters of the optical cavity, the neon buffer gas pressure, the reservoir and tube wall temperatures, and the parameters of the excitation circuit, of which the typical values were given in Ref.…”

“…Such a possible direct mechanism is the de-excitation of Cu metastables to the ground-state involving H . Since it is energetically favorable for the mutual neutralization process to leave Cu atoms in the excited levels [28] which rapidly relax to the metastable states by radiative decay, the metastable states form a "bottle neck" for the relaxing Cu species. The electron collisional deactivation, which is the main mechanism for de-excitation in conventional copper vapor lasers, is not so prevalent in the Cu HyBrID discharge due to the reduced free electron density.…”
