Abstract

Optical gain and photostability have been investigated for several orange/red rhodamine laser dyes (RLDs) doped in the polydimethylsiloxane and tetraethoxysilane derived organically modified silicate (PT-ORMOSIL) composites. The RLDs in PT-ORMOSILs exhibit gain and stability comparable to those in methanol solution while substantially better than in the PMMA matrix. Broadband laser oscillations have been achieved in a free-running resonator with Rh610/PT-ORMOSIL as the gain medium. The lasing threshold and slope efficiency are found to be approximately 8 (mu) J and approximately 30%, respectively.
