FemtoFiber pro TVIS tunable to any wavelength in the visible range

FemtoFiber pro TVIS – tunable 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.
