ABSTRACT:
A coupled ion laser operating at a frequency determined by the energy levels characteristic of the coupling of a lanthanide or actinide group ion with an iron group ion in an orthoaluminate material, such as yttrium orthoaluminate, is described in which low threshold high efficiency starting operation at predetermined frequencies in the region of eye safety is provided.
