Abstract
The lasing properties of rhodamine 6G dissolved in poly(2-hydroxyethyl methacrylate) matrices with different amounts of ethylene glycol dime thacrylate as crosslinking monomer are investigated. Increasing the ri gidity of the matrix by decreasing the polymer free volume results in significant increases of both lasing efficiency and photostability. Th ere exists an optimum degree of crosslinking for which efficiency and photostability reach the highest values.
