Abstract
A cooling device for a pulsed laser includes a cooling circuit with a cooling medium whose volume is increased in the pulsed excitation process. At least one inlet valve and at least one outlet valve are provided in the cooling circuit, and are dimensioned in dependence on the operating parameters of the laser such that at least a partial circulation of the cooling medium takes place in the cooling circuit due solely to the increase of the cooling medium volume in the excitation process, Separate pumps for the circulation of the cooling medium are dispensed with,
