ABSTRACT:
Coherent monochromatic radiation (laser light) in the wave length range of 450 to 560 nm is obtained by exciting with a pump light source a dyestuff solution containing a dyestuff of the formula ##STR1## wherein R.sub.1 represents hydrogen, alkyl, cycloalkyl, aralkyl, an alkylene radical linked to the 6-position of the coumarin ring system or, together with R.sub.2 and the nitrogen atom to which they are bonded, and optionally with inclusion of further heteroatoms as ring members, represents the remaining members of a heterocyclic ring system, R.sub.2 represents alkyl, aralkyl or an alkylene radical linked to the 8-position of the coumarin ring system and R.sub.3 represents hydrogen or an optionally substituted phenyl radical, the rings A and B can carry further substituents and a carbocyclic 5-membered or 6-membered ring can be fused to the ring B, in a solvent which does not interfere with the emission, at a concentration, which emits laser beams, of, preferably, 10.sup.-.sup.2 to 10.sup.-.sup.4 mol/liter.
