Congratulations to Dr. Andrews, Dr. Crescimanno, Dr. Mao, and Bijayandra Shakya! Their paper has been named one of the Top Downloaded Articles in Organics and Polymers from the Optical Materials Express journal for the last year. The paper, “Co-extruded mechanically tunable multilayer elastomer laser,” is a collection of experiments from a collaborative effort between YSU and Case Western Reserve. The abstract is below, but make sure to check out the full article at the Optical Materials Express website here!

“We have fabricated and studied mechanically tunable elastomer dye lasers constructed in large area sheets by a single-step layer-multiplying co-extrusion process. The laser films consist of a central dye-doped (Rhodamine-6G) elastomer layer between two 128-layer distributed Bragg reflector (DBR) films comprised of alternating elastomer layers with different refractive indices. The central gain layer is formed by folding the coextruded DBR film to enclose a dye-doped skin layer. By mechanically stretching the elastomer laser film from 0% to 19%, a tunable miniature laser source was obtained with ~50 nm continuous tunability from red to green. Optically pumped by a frequency-doubled Nd:YAG laser, the elastomer laser showed a lasing threshold of 0.9 mJ/cm2 at 600 nm.”
