Abstract

With the Er³⁺ doped crystals we are looking presently for high power laser materials operating in the eye-safe spectral region around 1.54 μm, with at least equivalent optical characteristics and laser performance - when codoped with Yb³⁺-but with better thermal properties than that of the commercially available Er-doped phosphate . glasses (such as Kigre QE-7 for example). With the Tm³⁺ doped systems, we are looking for materials for efficient diode-pumped mid infrared miniature lasers which can lase in a tunable mode in the 2 μm spectral region.
