FemtoFiber pro IRS

Ultrafast fiber laser @ 1570 nm center wavelength
Shortest pulse (<40 fs) at high power (>180 mW)
SAM mode locking, PM fiber based MOPA system
Robust and reliable design, push button operation
Compact footprint < Letter/A4 format

The FemtoFiber pro IRS is the short-pulse version of TOPTICA’s FemtoFiber pro IR. It comprises a very robust master-oscillator with power amplifier in one single box. With a prism compressor and a special non-linear fiber, shortest pulses at the fundamental wavelength of Er-doped fiber lasers are generated. The system allows optimizing the pulse characteristics manually to individual needs; alternatively the pulse length can be controlled by an automized feedback-loop.
