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.

Abstract: A silicon carbide cladding slab based laser cooling device is disclosed. The cooling device includes two silicon carbide slabs, two heat sinks and two fans. The first and the second silicon carbide slabs are respectively diffusion bonded to both sides of a Nd:YVO4 active material of a laser; the first and the second heat sinks are disposed on outer sides of the first and the second silicon carbide slabs, respectively; the first fan is facing the first heat sink and the second fan is facing the second heat sink. The present invention facilitates the operation and miniaturization of a high-energy Nd:YVO4 slab laser at room temperature and ensures a stable high-energy laser output of the slab laser, thus providing a solution for its commercialization.
