  • Patent number: 5109387
    Abstract: A dye laser system and method for operation thereof. The dye laser includes a laser cavity capable of lasing in response to an energy source, a circulation path for pumping a dye solution to the laser cavity, and a regeneration medium containing saturated dye solution at equilibrium with the concentration of the dye solution in the circulation path located in the circulation path so that the dye solution is regenerated by circulation through the regeneration medium. According to another aspect, there is provided a system and method for restoring dye solution degraded by use in dye laser. The system and method include a circulation path for conveying degraded dye solution to a regeneration medium containing a saturated dye solution at equilibrium with the concentration of the dye solution in the circulation path connected to the circulation path so that the dye solution in the circulation path may be regenerated by circulation through the regeneration medium.
