A device suitable for the implementation of a solution of a degradable of any product, for example of a saturable absorber, in particular for laser

摘要

The apparatus comprises a circulation circuit including, in series, a cell containing the degradable solution and a pump for circulating the solution. A second, regeneration circuit is connected to the circulation circuit by valves for injecting into the latter solution having a concentration greater than that of the circulation circuit. The regeneration circuit has a surge tank or a collector vessel for collecting degraded solution from the circulation circuit.
