Abstract

A control system for a dye laser is described, in which a pump pumps the dye from a supply vessel into a pressure vessel, in which there is an air pocket for damping vibrations, fluctuations in the pump delivery, etc. The dye passes out of the supply vessel as a jet via a nozzle. At least one sensor measures the dye filling level in the supply vessel and a control switches off the dye laser when the level in the supply vessel does not drop to the correct value after switching on the laser. The control system of the invention prevents the switching on of the laser if the level is too high or low before putting the laser into operation.
