Thin film dye laser based on BBQ doped poly (methyl meth-acrylate)‎

Abstract EN

This paper reports on the laser emission properties of the BBQ dye in poly (methyl meth-acrylate) (PMMA).

This host material combines the advantages of an organic environment for dye with the thermoptical mechanical properties of an organic dye.

A BBQ dye solid solution in PMMA polymer.

A nitrogen laser in untuned laser cavity has pumped thin films.

We developed the concentration and the thickness to get high efficiency.

The laser efficiency had been increased from 7 % at thickness 1.5 µm to 16.5 % at thickness 3.5 µm, and from 1 % to 10 % when concentration increased from 1x10-5M to 1x10-3 M.
