Abstract: A temperature controller is used for a gain fiber of a fiber amplifier. The controller includes a heat transfer structure and one or more temperature sinks, such as cooling plates. The heat transfer structure supports the gain fiber and is disposed in thermal contact with it. Portions of the temperature sink(s) are disposed in different thermal conductivity with sections of the heat transfer structure. For example, the sinks may have different material properties and/or material thicknesses. Also, portions of the temperature sink(s) can have different cooling rates. The different thermal conductivities conduct the heat from parts of the gain fiber differently from one another. In the end, an onset of Stimulated Brillouin Scattering (SBS) on the laser light path can be mitigated by conducting heat from the gain fiber with the different thermal conductivities.

Abstract: An apparatus is used for spectral beam combining laser wavelengths into a combined beam. The apparatus has an integrated, sealed optical assembly that can be installed and replaced in the field. The optical assembly has a housing composed of a material, such as fused silica, transparent to the laser wavelengths. Transmissive gratings are disposed on ends of the housing and have their datums facing the sealed interior. V-grooves on a shelf at one end of the housing are disposed at an angle relative to the first grating. Fiber ends of a fiber array have end caps affixed in the V-grooves and aligned to the datums of the first grating. The fiber ends transmit the laser wavelengths in an array of beams toward the first grating, which diffracts the laser wavelengths to the second grating. In turn, the second grating transmits the laser wavelengths as a combined beam from the second end of the housing.

Abstract: The present invention lies in the fields of chemistry and materials engineering. More specifically, the present invention describes a process of heat treatment of polymeric precursors including as active phases particle charge or a mixture of active phases with inert phases called “fillers”. It is also described a surface including ceramic polymer obtained by said process. The volumetric positive variation resulting from the formation of new phases, which for their formation, incorporate atoms from the gaseous phase, contributes to a minor shrinkage of the composition during the heat treatment process. The process of the present invention allows obtaining the desired phases in smaller treatment times and lower temperatures, when compared to a thermal treatment process as conventional pyrolysis (PC) due to the presence of highly reactive species, as for example atomic nitrogen produced by the dissociation of nitrogen molecules in the plasma environment.
