Research and development of Frit type edge cladding for GSGG laser crystals. Final technical report, July 1984-January 1985.

摘要

A glass compositional area has been defined in the system CuO-PbO-Bi(sub 2)O(sub 3)-Al(sub 2)O(sub 3)-SiO(sub 2) with thermal expansion coefficients of about 82--84 (times) 10(sup (minus)7)/(degree)C and refractive indices at 1.06 micron of about 1.93. Absorption coefficients are adjustable with CuO levels. These properties are required for a cladding glass for the edges of GSGG crystal slabs. Experiments with GSGG disks of 6 and 14 mm dia. have resulted in coatings of strong adhesion with glass crystal interfaces which are free of bubbles or devitrification. 4 refs., 11 figs., 14 tabs.
