Abstract

Air-cooled laser devices and formation methods are provided. An exemplary air-cooled laser device can include at least a laser active slab, a first silicon carbide clad, a second silicon carbide clad, a first laser diode array, and a first cylindrical lens. The first and second silicon carbide clads can be symmetrically bonded to the laser active slab and can have a surface area greater than the laser active slab to form an air duct surrounding side surfaces of the laser active slab and between the silicon carbide clads. The first laser diode array can emit first input pump laser beams to be collimated by the first cylindrical lens to provide parallel and quasi-parallel pump laser beams that are guided by the air duct to enter into the laser active slab from at least a first side surface of the laser active slab.
