This patent describes a lasing arrangement including a dye chamber defining a given zone having a cross sectional configuration which displays fixed lengthwise and widthwise dimensionals and through which a continuous stream of dye flows in one direction while the zone is being illuminated by light from a first pumping beam which is directed into the zone along a second direction and which causes the dye to laser within the zone. The arrangement also includes means to produce or amplify a dye beam extending in a third direction. The improvement described here comprises: (a) means for producing pump beams of lower power and different frequencies than the first pumping beam; (b) a light multiplexing assembly including optical fiber means having an output end for combining the lower power beams into a single beam which exits the optical fiber means at its output end and which serves as the first pumping beam; and (c) light coupling means connected with the output end of the optical fiber means for optically directing the first pumping beam into the dye chamber zone to illuminate the zone with light from the first pumping beam. The light coupling means includes optical means for causing substantially all of the light from the first pumping beam to be directed substantially uniformly into the cross sectional configuration. The optical means includes means for optically imaging one dimension of the first pumping beam, as the one dimension appears at the output end of the optical fiber means, into the widthwise dimension of the zone.
