ABSTRACT:
A solid state dye laser incorporating a polyacrylamide gelatin solid host is doped with a laser dye such as rhodamine 6G and pyrromethene 556. The host is aligned within a lasing cavity and is excited to fluorescence by a pumping laser such as a second harmonic Nd:YAG. A container made from pyrex or inorganic oxide glass can be used to encapsulate and protect the gel solid. The solid state dye host exhibits "self healing" after photobleaching due to dye migration within the encapsulated form.
