Abstract
Fluoride glasses singly and co-doped with Ho3+ and Er3+ ions have been synthesized. Using a conventional 800nm laser diode, intense mid-infrared emissions around 2μm, 1.55μm and 2.7μm are successfully obtained in present Ho3+/Er3+ co-doped ZBLAY fluoride glass. The optical properties and energy transfer mechanism for intense emissions are characterized. The 2μm emission lifetime of present glass can reach as high as 14.16ms. Based on the absorption, fluorescence spectra and lifetime measurements, it is found that Er3+ ions can transfer their energy to Ho3+ ions with high efficiency. Hence, Ho3+/Er3+ co-doped ZBLAY glass possessing advantageous spectroscopic characteristics is a potential cost-effective host for the mid-infrared solid state lasers.
