Adaptor element of field profile of signal branch of signal mergers and pumping, merger and optical device

摘要

ufeffvynu00e1lez provides adjustment member for adjusting the profile of the electromagnetic field signal branches for sluu010dovau010de signal and pump, in particular for the cladding pumped fiber lasers and amplifiers, containing the input optical fibre (1), at least one intermediate opti and fibre (4) and an output optical fiber (7),where the input optical fiber (1) has a tapered one end of the tapered end and is connected to the adjacent zuu017euju00edcu00edm with intermediate optical fibre (4) by a weld (5) between the input optical fiber and the intermediate optical fiber.the intermediate optical fiber (4) is in its zu00fau017eenu00e9m end associated with an output optical fibre (7) through the weld (6) between the output optical fiber and intermediate optical fiber. in the case of the presence of more intermediate optical fibres (4) are the intermediate optical fiber tapered and are also associated mezilehlu00fdmi welds (8) between the optical fibers.in place of each weld between two optical fibres is maximised pu0159ekryvovu00fd integral field profiles of these fibres. the solution provides sluu010dovau010d and optical device containing it. adjustment member and sluu010dovau010d may be used with advantage in various fields of technology, especially in high power laser systems for material processing, or for medical laser systems.
