Dual channel method for pumping and cooling lasers and laser device

John Darby Hewitt (Inventor), James Gary Eden (Inventor)

Research output: Patent

Abstract

A laser pumping method pumps a primary amount of energy into a laser medium to populate an intermediate level near an upper laser level. A lesser amount of energy is pumped into the laser medium to populate an excited level that lies above the upper laser level and transfers atomic or molecular population to the upper laser level by a nonradiative process. A laser device includes a laser medium supporting four levels, including a lower laser level, an upper laser level, an excited level above the laser level from which population transfers to the upper laser level via nonradiative transition, and an intermediate level within a few kT of the upper laser level.
