SOLID-STATE DYE-LASERS BASED ON POLYMERS INCORPORATING COVALENTLY BONDED MODIFIED RHODAMINE 6G

We report on the lasing action of modified rhodamine 6G dyes copolymer ized with methacrylic monomers. The laser samples were transversely pu mped with a N-2 laser at 337 nm. Lasing efficiencies similar to those found for rhodamine 6G in ethanol solution have been achieved. Importa nt increases in photostability, with lifetimes in excess of 20 000 sho ts at 2 Hz, have been obtained, By using a rotating mechanism, a stabl e output with no sign of degradation after half a million shots has be en demonstrated.
