摘要： The invention relates to sources of optical radiation wherein polarized radiation from first and second rows of light emitters is first collimated and combined into two combined beam using first and second rows of collimating and beam re-directing elements, respectively, and then polarization multiplexed to form a polarization-multiplexed output beam. In order to reduce the footprint, emitters of the first and second emitter rows are disposed in an interleaved, staggered arrangement, and the second row of collimating and beam re-directing elements is disposed in a space between the first emitter row and the first row of collimating and beam re-directing elements.

摘要： A molded ceramic or glass ferrule has at least one longitudinal passage, which enables an optical fiber feed through, sealed into a metal housing with glass solder. The metal material in the housing has a slightly higher coefficient of thermal expansion (CTE) than the ferrule material and the sealing glass so that hermetic seal is maintained by a compression stress applied to the ferrule and sealing glass by the housing at operating conditions. When the housing has to be fabricated from a low CTE material, e.g. metal or ceramic, a metal sleeve and stress relief bracket is used to apply the compression stress.

摘要： A gain-module for a laser resonator has an elongated gain-element located in an diffusely reflective cylindrical enclosure having an elongated entrance slit for admitting pump radiation. Pump radiation is supplied by two diode-laser arrays assemblies each including a fast-axis collimating lens. Propagation axes of the diode-laser array assemblies are at an angle to each other. The propagation axes extend through the entrance slit into the enclosure without being intercepted by the gain-element and with the gain-element being located between the propagation-axes.
