The application of sol gel process in the preparation of solid state dye lasers

The solid state dye lasers have many advantages.There are many ways to prepare them,and the sol gel process is a better one.But there still have many disadvantages in the old sol gel process which limits its application.This article discusses tow kinds of modified process-organically modified silicates (ORMOSILS) and incorporating polymethyl methacrylate(PMMA) into the sol gel matrix.By comparison of laser performance of dye molecules in ORMOSILS and PMMA host,we can see that ORMOSILS are a better host for organic dyes in the preparation of solid-state dye lasers.
