CALCIUM GALLIUM SULPHIDE (CaGa2S4) AS A HIGH GAIN ERBIUM HOST

摘要

The present invention uses a novel crystal host (12) to minimize parasitic upconversion and lifetime quenching processes by increasing the distance between active dopant ions in the matrix. As a result, erbium that could previously only be useful at low levels may now be incorporated at much higher concentrations without adverse effects. In addition, this host (12) has long excited-state-lifetimes, making it more effective as an energy storage device for pulsed laser applications.
