An investigation is made for the lasing characteristics and discharge phenomena of a pulsed nanosecond discharge plasma in an 80 mm-bore copper vapor laser (CVL).
Lasing characteristics are obtained by varying one of the lasing conditions of the test pulse (single shot pulse) waveform, the interpulse duration and the gas temperature keeping the tube temperature and hence the copper vapor density constant. It is found that the laser output power increases proportionally to the voltage across the plasma in the CVL discharge tube and that the plasma voltage or the recovery of plasma resistance during the interpulse duration is more important for the increase of laser output power than the population density of the metastable lower laser level.
