摘要： A fiber Raman laser is configured with a microstructured double clad passive fiber which has an inner cladding receiving and guiding a high intensity pump light. The double-clad passive fiber farther has a eon surrounded by the inner cladding and an outer cladding. An arrangement of air holes is configured to define the inner, waveguiding cladding so that an NA of the latter varies between about 0.25-0.9 allowing this to reduce the diameter of the inner cladding. The passive fiber is characterized by a substantial overlap between the pump light and 1st stokes in the care and further includes an absorber operative to substantially suppress the signal light at the 2nd strokes so that the Ge-doped fiber outputs a SM, bright radiation at up to kW levels.

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 cost-effective short laser-pulses using fibers with anomalous dispersion and high non-linear 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 photonic crystal fiber arranged to provide guidance of light in the core region due to the photonic bandgap effect (PBG), where light propagates in a hollow or solid core surrounded by a Silica cladding comprising a substantially periodic distribution of micro-structural elements, and where the refractive index of the core is lower than the effective 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.
