摘要：
We report a new low loss silicate bonding method for the assembly of laser materials. Original heterogeneous composite laser crystals have been obtained thanks to this sot-gel method: Er/Yb phosphate glass parallel to sapphire and Nd:YVO4 parallel to sapphire. Sol composition containing additives enables to bond chemically and thermo-mechanically different materials. Composite materials made with KH2PO4 rich sot-gel demonstrated the best temperature resistance. Potassium and phosphate ions add extra flexibility and chemical affinity. The bond is resistant to temperatures higher than 200 degrees C and laser actions have been demonstrated in both composite materials for the first time. (C) 2010 Elsevier B.V. All rights reserved.
