A copper vapor laser by using a copper-vapor-complex reaction at a low temperature

A copper vapor laser performance by using a metal-vapor-complex reaction (Cu+AlBr3) is reported. The laser operation is obtained at a low temperature without external heating because of the AlBr3 vapors evaporating at a room temperature. The copper vapor laser using this metal-vapor-complex reaction has an advantage of deposition-free of a metallic copper to the laser tube wall, which is different from the copper halide and the organometallic copper lasers
