FemtoFiber pro NIR: Near-Infrared Femtosecond Fiber Laser

Ultrafast pulses (< 100 fs)
Highest output power (> 140 mW @ 780 nm)
Free-beam output switchable between 780 / 1560 nm
SAM mode-locked oscillator and amplifier system (MOPA design)
Alignment-free all-fiber setup with telcordia proved components
Only polarization maintaining fiber components
Second harmonic generation by periodically-poled Li:NbO3-crystal
No air or water cooling required
Robust and reliable design
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 to optimize the pulse characteristics to individual needs either at 1560 or 780 nm.
