The FemtoFiber ultra 920 is a new and unique member of Toptica’s third generation fiber lasers. It provides pulses centered at 920 nm with a duration of typical below 100 fs and a repetition rate of 80 MHz.

The system reaches an average power of more than 1 W wich is a record-breaking achievment in conjunction with the short pulses at same time. The pulses are generated using a SESAM-mode locked ring-type Erbium-based fiber oscillator, followed by a patent-pending high-power fiber amplifier. For reaching highest reliability levels, only polarization-maintaining fibers are used in the signal path.

The FemtoFiber ultra 920 provides a small laser head with a footprint of 23 x 15.5 cm2. The laser head is designed to ensure minimum heat dissipation to its environment and therefore provides also highest stability for beam pointing. For more flexibility, the design also allows mounting the laser head into an integrators environment, even under various orientations (vertical/ horizontal/…). The laser system comes with an 19“-type standard rack (3 units height) control and supply unit which is connected via detachable fiber and electronic lines of typ. 2 meters length.

The system is controlled either manually by a simple emission push-button operation and also provides all necessary safety features complying with the latest laser safety regulations. Furthermore, the laser system can also be remote-controlled via Ethernet or USB. A simple graphics user interface (GUI) enables user-friendly access to all laser parameters.

The FemtoFiber ultra 920 shares the advantages of Toptica's previous ultrafast fiber laser generations. lt is a compact laser system and works reliable just after a push-button start. No water-cooling is required, simple forced air convection cooling of the control/supply unit is suffcient for stable operation of the system. lt 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.

The laser system is a great solution for applications in non-linear microscopy like two-photon excitation of fuorescent proteins and SHG based contrast mechanisms.

With the emission wavelength of 920 nm it provides highest power for especially green and yellow fluorescent protein markers (GFP, YFP) commonly used e.g. in neurosciences and other laser-related biophotonic disciplines. lt perfectly closes the wavelength gap in between the already existing FemtoFiber ultra systems at 780 and 1050 nm.
