Abstract.

 Rhodamine B (Rh-B) has been embedded in PolyAcrylic acid (PAA) films. The materials are studied for the laser action with nitrogen laser excitation. The lasing efficiency of Rh-B/PAA films is comparable to that of rhodamine 6G in methanol. There is a 50% reduction in the laser intensity of the films with 2600 pulses from the N2 laser (2 Hz). The photostability of these materials is far superior to that of other polymeric materials and is comparable to that of sol–gel materials.
