Improved lasing lifetime of de-oxygenated xerogels doped with pyrromethene dye

Summary form only given. In the search of all-solid-state tunable lasers in the visible, solid-state dye lasers are promising tools. Both polymer and xerogel can be host matrices for organic dyes. A lot of research has been done in order to improve the photostability and thermostability of the organic molecules encaged in the matrix by using new molecules such as pyrromethenes or perylenes. Also, new matrices with less dopants mobility and better thermal conductivity have been recently developed to reduce the degradation of the dyes. In this communication, we report on new dye-doped xerogel matrices that fulfil the requirements needed for efficient and long lifetime amplifying media.
