Frequency-doubled Femtosecond Erbium Fiber Laser: FemtoFErb 780

Erbium fiber laser based on SAM technology
Second harmonic generation by periodically-poled Li:NbO3-crystal
100 MHz repetition rate
Free-beam delivery with > 50 mW output power
< 230 fs (typ. 200 fs) pulse width
Alignment-free all-fiber setup with telcordia proved components
Only polarization maintaining fiber components
No air or water cooling required
Robust and cost-effective design
Compact footprint and turnkey operation

The FemtoFErb 780nm is a very compact all fiber-based femtosecond laser system with excellent amplitude and frequency jitter parameters. It unites both supply electronics and laser unit 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.
