- Abstract
- Effects of CsI content on the optical properties of Ge30Ga5Sb5Se60 glasses were evaluated. Linear and non-linear absorption properties of the glasses without Pr3+ were examined in addition to 1.6 mu m emission properties of the Pr-doped glasses. Blueshift of the UV-side absorption edge was accompanied with increasing CsI concentration, while non-linear absorption coefficients measured at 1.06 mu m by the Z-scan method remained unaffected. Measured lifetimes of the 1.6 mu m emission from modified glasses were comparable to those of the unmodified glass. These experimental observations are discussed in connection with a pronounced weak absorption tail appeared in selenide glasses with the addition of CsI. (C) 2007 Elsevier B.V. All rights reserved.
