Abstract
A laser module has a unitary base including stepped platforms with an offset relative to an adjacent platform, each stepped platform accommodating a laser source with at least a first and a second plurality of stepped platforms, each platform accommodating a cooling channel inside at a predetermined depth below the top surface of the platform to conduct a flow of cooling fluid provided on an inlet, the cooling channel running under a platform having microchannels, the cooling channels being connected to a fluid inlet with an inlet manifold that provides cooling fluid at the inlet and an outlet manifold to dispose the cooling fluid with waste heat at an outlet, the laser module producing in one embodiment no less than 100 Watt of optical power.
