Laser oscillation on the 780.8 nm copper ion line was investigated using capaciteve coupled radio frequency (CCRF) discharge excitation. Laser action was obtained at cw, quasi-cw and pulsed mode of excitation. The optimal for lasing conditions were determined. A small-signal gain of 25%/m was measured at optimum laser conditions. The high gain and the stable operation offer good possibilities for UV lasing in Ne-Cu CCRF-excited discharge.
