Abstract
Here we report on the possible application of starch as a dye-doped biopolymeric matrix designed for random lasing generation. Gelatinized biopolymer doped with Rhodamine 6G was used as light amplification medium as well as source of positive feedback which is originating from high surface roughness fluctuations. It is demonstrated that, applying the starch as a matrix for laser dye we can significantly increase photostability of laser emission with respect to other biopolymeric based systems which is great advantage of this material.
