Abstract
Today, a series of pulsed lasers is known, which operate at transitions from a resonance to metastable level in metal atoms and ions. The most efficient and producing the highest output power in the visible region among all, is the copper vapor laser (CVL). Practically an efficiency of up to 1.5% and an average power of the order of 500 W are already achieved. One of the main difficulties for CVLs is imposed by the necessity to provide a sufficient concentration of copper atoms in the active volume. The temperature guaranteeing such copper atom concentration is ~1500C and that requires high-temperature materials for constructing laser tubes. The high temperature causes not only technical difficulties but also complications of a more general nature, since the lower laser levels that are metastable, can be significantly populated at high temperatures. The difficulties associated with introducing the Cu atoms into the active volume by heating have compelled researchers to seek other methods for creating a high density of copper atoms in the active volume.
