Abstract
A dye laser fluid dye solution replenishment system in which the portion of the lasing fluid passing through the laser head which has been activated to a lasing condition is separated from the remainder of the unactivated dye solution and is separately restored before being recombined into the fluid flow path. The thus separated and degraded dye solution, representing only the degraded component of the flowing dye solution, is filtered to remove the degradation products and restored to the desired dye solution component concentrations. The thus restored solution is reinserted into the fluid flow path through the laser head.
