FemtoFiber pro TVIS
Tunable Pulsed Fiber Laser
• Tunable visible fiber laser @ 488 - 640 nm • High spectral purity due to selective SHG process
• SAM mode locking, PM fiber based MOPA system • Robust and reliable design, push-button operation • Free beam output
The FemtoFiber pro TVIS is the model of the FemtoFiber pro series that yields tunable visible sub-picosecond pulses from 488 nm to 640 nm. It comprises a very robust SAM mode-locked master-oscillator and a core-pumped high power amplifier. The supercontinuum generated in a highly nonlinear fiber (HNLF) is frequency converted by a manually tunable SHG crystal. Two motorized prism compressors allow adjustment of the supercontinuum and the optimization of the pulse width. The wavelength tuning is done by a manual micrometer screw and allows a continuous wavelength change by a fan-out structured crystal.
Applications
• Fluorescence Lifetime Imaging Microscopy
• Widely tunable visible light source
• Pump-probe spectroscopy (in combination with a second system/multiple beam configuration)
