FABRICATION TECHNOLOGY AND LASER OSCILLATION OF LEAD-TIN FLUOROPHOSPHATE GLASS DOPED WITH RHODAMINE 6G DYE

The fabrication technological processes of lead-tin fluorophosphate optical glass were studied systematically, and the optimum results of several key techniques, including raw material selection, crucibles adoption and determination of atmosphere gases, temperature and time conditions for the melting process are presented in this paper. Using the optimum technique, the influence of glass systems and composition on the glass transition temperature, chemical durability and optical transmittance was also investigated. The optimized base glass for doping rhodamine 6G dye was determined to be 20SnO-50SnF 2-30P 2O 5-5PbO. A two_crucible method for doping the dye homogeneously in this low_melting glass without any thermal decomposition was used and the technological condition was optimized. The optical and luminescent properties of this dye contained complex glass were analyzed. The successful solid_state dye laser oscillation of rhodamine 6G with this complex glass pumped by a frequency doubled Nd:YAG laser at 532 nm was achieved for the first time. The output laser wavelength centered at 582.8 nm ranges from 554 nm up to 614.2 nm.
