ABSTRACT:
A metal vapor laser which can produce two or more discrete outputs from a single vacuum chamber. This is achieved by using two or more different materials and by confining each material to its own area so that the materials do not mix one with the other and optimum lasing performance can be obtained from each material. All the lasing areas have a common optical axis. The lasing outputs can be produced separately or mixed together as required.
