International Classification:

H01S 320

US Classification:

331 945L

Abstract:

A dye laser comprising a laser dye solution of a compound having the general structure: ##STR1## wherein at least one of the 5, 6 and 8 ring positions is occupied by a nitrogen atom in lieu of the corresponding CR group and X is OH, alkoxy, or amino including amino substituted by at least one of the following: alkyl, aryl, acyl, aracyl, a group which taken together with the nitrogen atom of the amino group forms a heterocyclic ring, or part of one or two 5 or 6 membered aliphatic heterocyclic rings attached to ring A at positions 6 or 8 or both depending on where the N in ring A is located. R. sub. 3, R. sub. 4, R. sub. 5, R. sub. 6 and R. sub. 8 are hydrogen or other groups as defined below. The compounds lase in the blue-green to near ultraviolet region.
