Abstract
The invention relates to a marking apparatus for marking an object with laser light, which apparatus comprises at least one gas laser for emitting at least one laser beam for marking the object. The at least one gas laser comprises a plurality of resonator tubes (12) for receiving a laser gas, a plurality of heat dissipaters (20) for dissipating heat from the resonator tubes (12) is provided, each resonator tube (12) is thermally connected to one of the heat dissipaters (20), and each heat dissipater (20) comprises microchannels for receiving a cooling fluid.

A marking apparatus for marking an object with laser light, comprising:
- at least one gas laser for emitting at least one laser beam for marking the object,
- wherein the at least one gas laser comprises a plurality of resonator tubes for receiving a laser gas,
- wherein a plurality of heat dissipaters for dissipating heat from the resonator tubes is provided,
- wherein each resonator tube is thermally connected to one of the heat dissipaters,
- wherein:
- each heat dissipater includes microchannels for receiving a cooling fluid, the microchannels' smaller dimension being less than 2 millimeters, and
- at least one wall of each microchannel has perturbations such that the cooling fluid exhibits a turbulent like flow.
