COOLING DEVICE FOR COOLING A LASER ARRANGEMENT AND LASER SYSTEM COMPRISING COOLING DEVICES

摘要

The invention describes a cooling device (100) for cooling a laser arrangement and a laser system comprising at least two of such cooling devices (100). The invention further describes a method of manufacturing the cooling device (100) and the laser system. The cooling device (100) comprises a mounting area for the laser arrangement, a cooling volume (140) comprising cooling channels being arranged to cool the mounting area (105), a coolant inlet and a coolant outlet (150,145) being connected to the cooling channels of the cooling volume (140), a first coolant supply through hole (110) being connected to the coolant inlet (150), a second coolant supply through hole (111) being connected to the coolant outlet (145). The cooling device (100) further comprises at least one coupling element (115, 130, 135) enabling a detachable interconnection to a second cooling device (100) such that upon interconnecting the cooling device (100) to the second cooling device (100), the first coolant supply through hole (110) of the cooling device (100) being connected to a first coolant supply through hole of the second cooling device (100) and the second coolant supply through hole (111) of the cooling device (100) being connected to a second coolant supply through hole of the second cooling device (100), wherein the cooling device (100) being arranged in a way that a coolant can be supplied to the cooling volume via the first coolant supply through hole (110) and the second coolant supply through hole (111). The cooling device (100) enables a cost effective and scalable laser system.
