ABSTRACT:
This application discloses light amplification apparatus in which population inversion is created in which energized particles collide with a lasing medium to create a population inversion. In the preferred embodiment the energized particles are atoms, ions, or molecules different than the lasing medium which are excited to a long-lived state above the ground state. Various materials usable in such light amplification apparatus are disclosed as well as means for passing light through an amplification region.
