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.
Applications
• Tunable CARS laser source (in combination with FemtoFiber pro NIR/multiple beam configuration, and long pulse option)
• Widely tunable near-infrared light source
• Pump-probe spectroscopy (in combination with a second system/multiple beam configuration)
