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.

SwitchBox
The FemtoFiber smart SwitchBox is a small tool for quick starters. It provides all switches, supply and status lines to run every FemtoFiber smart 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).
