摘要:
Dyestuff laser consisting of a reservoir, with a laser dyestuff solution contained therein, and a pumped light source associated therewith, which is capable of exciting the dyestuff solution to produce an emission, characterized in that the dyestuff solution contains, in a solvent which does not interfere with the emission, a dyestuff which, in the form of the free acid, corresponds to the general formula ##STR1## wherein R.sub.1 to R.sub.4 independently of one another represent hydrogen, alkyl, trifluormethyl, alkoxy, aralkoxy, alkenyloxy, halogen or the carboxyl, cyano, alkylsulphone, aryl-sulphone, carboxamide, sulphonamide or carboxylic acid ester group,R.sub.1 and R.sub.4 can additionally denote a fused-on benzene ring,n represents a number 2 to 6 ando, p, q and r independently of one another represent 0, 1 or 2,in a concentration, preferably of 10.sup.-2 to 10.sup.-5 mol/1, which emits laser radiation.
