FemtoFiber ultra

High-power ultrafast fiber lasers

The FemtoFiber ultra series is TOPTICA's third generation of ultrafast fiber lasers. These lasers provide powerful femtosecond pulses with a ultra-high reliability. The systems use SESAM-mode locked ring fiber oscillators (patented design), followed by a high-power fiber amplifier. For reaching highest reliability levels, only polarization-maintaining fibers are used. All of this is integrated in a unit with a footprint of 25 x 38 cm². The laser systems are 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. The systems are compact lasers that work reliable just after a push-button start. No water-cooling is required since a simple air-cooling is sufficient for a stable operation. These cost-effective and compact laser solutions provide femtosecond pulses with high average power with an excellent beam quality. They are great solution for applications in nonlinear microscopy like effective two-photon excitation of fluorescent proteins and SHG based contrast mechanisms.
