摘要： A large mode area optical fiber includes a large diameter core (d1 up to 60µm), and a first cladding (diameter d2) wherein the difference between refractive index (n1 ) in the core and the first cladding (n2) is very small (?n 0.4) (n3 is preferably less than 1.3). The small change in refractive index between the core and inner cladding combined with a large change in refractive index between the first cladding and second cladding provides a significantly improved single mode holding waveguide.

摘要： A monolithic fiber is configured with a double bottleneck-shaped multimode (MM) core capable of supporting substantially only a fundamental mode at a given wavelength and having opposite end regions, frustoconically shaped transformer regions, which run inwards from the respective end regions, and a central uniformly dimensioned region, which bridges the transformer regions. The MM core has a refractive step-index profile which is configured with a centrally positioned dip having a variable width along the length of the fiber. The width of the dip is relatively small at the end regions of the MM core so as to support only the fundamental mode with a Gaussian profile. As the dip becomes larger along the input transformer region, it gradually shapes the Gaussian profile into the ring profile of the fundamental mode, which is guided along the central region of the MM core. The dip gradually becomes smaller along the output transition region so as to shape the ring profile back into the substantially Gaussian profile of the fundamental mode radiated from the output end region of the MM core. The refractive index profile has a ring area doped with one or more rare-earth elements and configured to amplify substantially only the fundamental mode.

The latter is configured to increase a threshold for nonlinear effects in general and in particular for stimulated Raman scattering (SRS) so that the delivery passive fiber has a fiber length at least twice the length of a delivery passive fiber with a standard unifomily dimensioned core, which may be used with the same laser source, while outputting the kW-power light with an M2 factor less than 2.

摘要： A fiber laser system enables a method for treating a semiconductor material by preheating a wafer for laser annealing and gas immersion laser doping by a laser source. A long wave length fiber laser having a Gaussian or similar profile is applied in a full-width ribbon beam across an incident wafer. Preferably the wavelength is greater than 1 mum (micron) and preferably a Yb doped fiber laser is used. The process is performed in a suitable environment which may include doping species. The process ensures the temperature gradient arising during processing does not exceed a value that results in fracture of the wafer while also reducing the amount of laser radiation, required to achieve controlled surface melting, recrystallization and cooling.
