Abstract: 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.
