摘要： The inventive system for crystallizing an amorphous silicon (a-Si) film is configured with a quasi-continuous wave fiber laser source operative to emit a film irradiating pulsed beam. The fiber laser source is operative to emit a plurality of non-repetitive pulses incident on the a-Si. In particular, the fiber laser is operative to emit multiple discrete packets of film irradiating light at a burst repetition rate (BRR), and a plurality of pulses within each packet emitted at a pulse repetition rate (PRR) which is higher than the BRR. The pulse energy, pulse duration of each pulse and the PRR are controlled so that each packet has a desired packet temporal power profile (W/cm2) and packet energy sufficient to provide transformation of a-Si to polysilicon (p-Si) at each location of the film which is exposed to at least one packets.

摘要： A high power fiber laser system includes a booster which is configured as a fiber amplifier extending over free space, pump source and laser head including a reflective element which receives pump light and. reflects toward the output end of the booster in a counter signal- propagating direction. The booster is configured with concentric and coextending frustoconically shaped multimode ("MM") core and cladding around the core. The core includes a mode transition region expanding between small diameter SM input and large diameter MM output core ends and configured so that amplification of high order modes is substantially suppressed as a single mode ("SM") signal light propagates from the input to output core ends. The laser head receives output, ends of respective pump light delivery fibers and signal fiber, respectively. The pump source is structured with a plurality of independent sub-pumps arranged around the booster. The laser head supports a segmented mirror configured to reflect pump lights from respective pump sub-sources to the output end of the booster in a counter propagating direction, wherein the booster is configured to emit the amplified signal light reaching up to MW power levels substantially in the SM.

摘要： The invention relates to an arrangement for supplying luminous energy to biological structures, comprising a pumping light source and/or a laser source, an optical beam forming system, and an optical waveguide which is coupled to the beam forming device to create a light intensity profile dependent on the full length of the waveguide and/or a change in shape and which comprises a core and a cladding surrounding the core, a distal fiber end being free. The arrangement is characterized by a depressed refractive index structure which extends across the core and the cladding and consists of a succession of concentric zones that are designed, in at least some sections in the radial direction, as an alternating succession of regions having a relatively low refractive index and a relatively high refractive index. In a method for producing an optical waveguide for an arrangement for supplying luminous energy in a targeted manner to biological structures, a diffractive index profile that is variable in the longitudinal direction of the optical waveguide is created by providing a glass tube having a first refractive index, coating the glass tube with at least one coating having a second refractive index, drawing the coated glass tube to create a capillary, and collapsing the capillary within a specific area and along a specific length to create a collapsed section.

摘要： A fiber block is configured with a fiber block including a Nd-doped active fiber and a pump-light delivery fiber which has a stretch extending along the active fiber in a side-to-side configuration so as to lunch pump light into the Nd-doped core of the active fiber. The core of the active fiber is surrounded by at least one or more claddings which, like the core, have a double bottleneck cross-section with a relatively large-area central region and relatively small input and output regions. The pump light delivery fiber is structured to have a substantially dumbbell cross-section with a relatively small-area central region coextending with the central region of the active fibers. The active fiber is dimensioned so that the overall length of the active fiber is configured to provide for the maximal amplification of the laser signal in a 900 nm range while limiting amplification in the 1060 nm range to the preset threshold. The fiber block is further configured so as to have the major fraction of the unabsorbed light, supported in the relatively large-area output end region of the passive fiber, be further used for pumping a neighboring fiber block.
