FemtoFErb 1560 FD6.5

Compact, pigtailed Er fiber laser

  • 6.5 meter fiber length (standard)
  • Single-mode, polarization-maintaining fibers
  • Dispersion compensation integrated in laser head
  • Short pulses (typ. 50 fs) at fiber output
  • FC/APC connectors on external fibers, detachable

The FemtoFErb 1560 FD6.5 provides excellent pulse characteristics after several meters output fiber (default 6.5 meters). This option allows replacing complex beam delivery setups by flexible and convenient optical fiber solutions. The FemtoFErb 1560 FD6.5 provides a laser ideally suited for time-domain THz applications. Further applications benefiting from the most stable, compact and cost-effective FemtoFErb 1560 FD6.5 are e.g. medical applications like endoscopy, metrology systems or optical inspection systems where a flexible beam delivery is required.

    • Fiber patch cable with mechanical protection (metal jacket)
    • Different repetition rate on request
    • Power Stabilization (option “P-STAB”) additional detector and close loop electronics for active power stabilization

     

    Different output fiber lengths (up to 25 meters) on request
    Shortest pulses available even after 25m fiber delivery (FemtoFErb 1560 FD25 customized system, dual output ports with 50:50 power split ratio)

     

    SwitchBox
    The FemtoFiber pro SwitchBox is a small tool for quick starters. It provides all switches, supply and status lines to run a PicoFYb as a stand-alone system without integration environment and therefore is especially recommended for single-system users.

    TOPAS: Graphical User Interface
    The new TOPAS GUI allows to operate the FemtoFErb 1560 in a convenient way via USB. All you need is to download and install the setup wizard program (see Download section).
