FemtoFiber pro NIR
Near-Infrared Femtosecond Fiber Laser
- Ultrafast fiber laser @ 1560 and 780 nm
- Fundamental or SHG output: manually switchable
- SAM mode locking, PM fiber based MOPA system
- Robust and reliable design, push button operation
- Compact footprint < Letter/A4 format
The FemtoFiber pro NIR comprises both fundamental wavelength 1560 nm and the second-harmonic 780 nm from a single box, with highest power and shortest pulses for fiber lasers in the market. The user can switch between both wavelengths without any re-alignment. Furthermore, a built-in motorized prism compressor allows optimizing the pulse characteristics to individual needs either at 1560 or 780 nm. The system is ideally suited for THz researchers, for Biophotonics applications (e.g. SHG imaging) and for two-photon polymerization.
