FemtoFiber smart 780

Compact High power Er fiber laser

  • Up to 140 mW avg. power with typ. 85 fs pulses
  • Alignment-free all-fiber setup, use of PM fibers only
  • Free-beam output with excellent TEM00 mode
  • Compact design: optics and electronics just in one box
  • Low power consumption

The FemtoFiber smart 780 is a powerful and very compact all fiber-based femtosecond laser system with excellent laser pulse and beam characteristics. It unites both supply electronics, fiber laser optics and second harmonic generation in one box, being thus one of the smallest fiber laser units on the market. The system only needs 12V power supply and comprises a free-beam output with mechanical shutter.

    SwitchBox

    The FemtoFiber smart SwitchBox is a small tool for quick starters. It provides all switches, supply and status lines to run a FemtoFiber smart as a stand-alone system without integration environment and therefore is especially recommended for single-system users.
