摘要： 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.

摘要： An excitation unit for a fiber laser having an excitation fiber and forming a two-dimensional or three-dimensional structure in a resonator region of the fiber laser. In cross-section, the excitation fiber has an active fiber core, a pump cladding that surrounds the active core, a quartz glass casing that surrounds the pump cladding, and at least one cover. The resonator region is equipped with a base plate having a plurality of excitation housings, each housing delimiting a gas-tight excitation chamber. The excitation fiber runs through each excitation chamber and is held in holding units. The excitation chambers are formed in an elliptical manner. The excitation housings are provided with a translucent window, and a transversal pump light source is arranged in the region of each translucent window such that a pump light that leaves the pump light source impinges the longitudinal axis of the excitation fiber in a perpendicular manner.
