摘要： The present invention deals with optical systems for providing short laser pulses. An object of the invention is to provide an optical system providing compact and costeffective short laser-pulses using fibers with anomalous dispersion and high nonlinear thresholds. The object is achieved by a short pulse optical system for generating or processing short laser-pulses, said optical system comprises an optical fiber in the form of a hollow photonic crystal air-guiding fiber (PBG), where light propagates in a hollow core surrounded by a Silica cladding and where the refractive index of the core is lower than the refractive index of the cladding. The invention may be useful in applications such as laser-based micromachining, thin-film formation, laser cleaning, in medicine and biology.

摘要： An optical fibre having a periodicidal cladding structure provididing a photonic band gap structure with superior qualities. The periodical structure being one wherein high index areas are defined and wherein these are separated using a number of methods. One such method is the introduction of additional low index elements, another method is providing elongated elements deformed in relation to a circular cross section. Also described is a cladding structure comprising elongated elements of a material having an index of refraction higher than that of the material adjacent thereto. Using this additional material, prior art structures may obtain much better qualities.
