FemtoFiber ultra 920 – Powerful Femtosecond Fiber Laser

920 nm High-power Ultrafast Erbium Fiber Laser System

  • Ultrafast fiber laser @ 920 nm
  • Unique approach: < 100 fs with > 1.5 W power
  • SAM mode locking, PM fiber based MOPA system
  • Robust, reliable, compact, cost-effective, push-button
  • Air cooled system, < 150 W power consumption

The FemtoFiber ultra 920 is a new member of TOPTICA's third generation of ultrafast fiber lasers. The system delivers laser pulses of less than 100 fs in duration at a central wavelength of 920 nm. The system provides more than 1 W average output power. It is a compact femtosecond laser system with turnkey operation and cost-effective design.

The pulses are generated using a SAM-mode-locked ring fiber oscillator (patented design), followed by a high-power fiber amplifier. For reaching highest reliability levels, only polarization-maintaining,  Erbium-doped fibers are used.

The oscillator and (pre-)amplifier generate pulses at a fundamental wavelength of 1560 nm. Depending on the model, different high-power amplifiers are boosting the output power. All of this is integrated in a unit with a footprint of 25 x 38 cm².  The laser system is easily controlled via Ethernet or USB. A simple graphics user interface (GUI) enables user-friendly access to all  laser parameters.

The FemtoFiber ultra series shares the advantages of TOPTICA’s previous ultrafast fiber laser generations. It is a compact laser system and works reliable just after a push-button start. No water-cooling is required since a simple air-cooling is sufficient for a stable operation of the system. It is a cost-effective and compact laser system that provides femtosecond pulses with high average power in the near-infrared with an excellent beam quality.  It is a great solution for applications in nonlinear microscopy like effective two-photon excitation of fluorescent proteins and SHG based contrast mechanisms.
