Spectral tunability between 830 and 1100 nm
FemtoFiber pro TNIR
Tunable Pulsed Fiber Laser
- Tunable near infrared fiber laser @ 830-1100 nm
- Solitonic laser source with short pulses < 250 fs
- SAM mode locking, PM fiber based MOPA system
- High spectral purity due to selective SHG process
- Robust and reliable design, push-button operation
The FemtoFiber pro TNIR yields a continuously tunable near-infrared femtosecond pulses from 830 nm to 1100 nm. The system comprises an all fiber master-oscillator with subsequent power amplification. A highly nonlinear fiber generates the supercontinuum which is frequency doubled by a manually tunable SHG crystal. A motorized prism compressor allows a fine pulse shape optimization for the selected wavelength. The wavelength tuning is done by a manual micrometer screw and allows a continuous wavelength change by a fan-out structured crystal.
