Abstract
The laser characteristics of a new dye, 7-Diethyl-amino-3-Styryl Benzi midazo (1,2-a) Quinoline (DSBQ) have been investigated in two solvents : DiMethylSulfoxide (DMSO) and DiMethylFormamide (DMF) by excitation w ith a pulsed nitrogen laser and compared with that of the standard dye rhodamine B. The lasing range of the dye is nearly 40 nm with maxima at 635 nm and 625 nm in DMSO and DMF, respectively. The efficiency of this dye (DSBQ) has been found to be better than half that of rhodamin e B.
