Abstract
A new hybrid organic-inorganic material has been developed which has excellent properties as an optical material and host for molecular dopants. The undoped material has very low optical loss at 1.06, 1.3, and 1.55 micrometers as well as in the visible region. In addition, a 20 mW HeNe laser beam directed through the sample is barely visible. The structure of this material has been studied using 29Si MAS-NMR, high-resolution TEM, and NIR spectroscopy. These results are presented and discussed in terms of the chemical composition, processing conditions and low optical loss of the material. A wide variety of molecular dopants has been successfully incorporated into this host. The linear optical properties of several perylene laser dyes and metal dithiolene (Chi) 3 molecules are presented. Results for lasing experiments, damage threshold, and (Chi) 3 measurements are being reported separately.
