    • Additional Information
    • Options
      Optical Isolation Single Stage
      Isolators are used to protect the laser diode from back reflections. Fiber coupling with angle polished fibers (both ends) requires at least a single stage isolator.
      Optical Isolation Double Stage
      Double stage isolators are needed if reflections from the experiment into the laser are expected. Fiber coupling with non-angle polished fibers also requires a double stage isolator.
      TOPTICA's patented fiber coupler provides highest single-mode fiber coupling efficiencies, easy alignment and at the same time highest stability. TOPTICA additionally offers a wide range of single-mode and polarization maintaining fibers, including fiber-optic beam splitters. Optical isolation is mandatory for fiber coupled diode laser systems.
