A perylene derivative dye, BASF 241, was impregnated into a composite sol-gel glass, and tested as a laser material. Laser tunability was obtained in the range 568 - 583 nm using a 532 nm pump beam (a frequency doubled Nd:YAG laser). Maximum efficiency of 7.4% was obtained at 575 nm. The laser threshold, was about 60 μJ/pulse.
