Toptica FemtoFiber ultra 920 – 920nm femtosecond laser for GFP and YFP imaging

• 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

920 nm High-power Ultrafast Erbium Fiber Laser System

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.

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 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.

It provides a tunable broadband output in the wavelength range of 5 to 15 µm (20 - 60 THz, 670 - 2000 cm-1). The unique 400 cm-1 broad emission spectra allow to excite a wide range of materials at the same time.  The air-cooled system is based on TOPTICAs proprietary fiber laser technologies and includes a difference frequency generation (DFG) unit as well as all necessary electronics into the same box. All functions and features are computer controllable by Ethernet or USB interfaces.

Reach high power levels with TOPTICA’s next generation femtosecond fiber lasers

TOPTICA’s FemtoFiber ultra NIR provides powerful femtosecond pulses of more than 500 mW and less than 150 fs at 780 nm.

The FemtoFiber ultra NIR from TOPTICA is a cost-effective, turnkey laser system that provides femtosecond laser pulses of more than 500 mW average power and an excellent beam quality. It is a powerful solution for applications in nonlinear microscopy like effective two-photon excitation of fluorescent proteins and SHG based contrast mechanisms, as well as micro-lithography. Experiments in fundamental physics will also benefit from the high output power of the laser. It provides pulses with a spectrum centered at 780 nm and a duration below 150 fs.

The system integrates a patented SESAM-mode-locked fiber-ring oscillator and a new high-power fiber amplifier. Polarization-maintaining, active fibers are used in order to maintain the highest reliability levels. Based on a fundamental wavelength of 1560 nm with a repetition rate of 80 MHz for oscillator and amplifier, the FemtoFiber ultra NIR uses a frequency-doubling stage, which converts the amplified output spectrum to 780 nm. Due to a highly efficient frequency-conversion process, more than 500 mW average power is available at 780 nm with a clean TEM00-mode free-space output.

Toptica: Powerful femtosecond pulses at 1030 nm!

TOPTICA expands their portfolio of ultrafast fiber-based laser systems.

TOPTICA's new FemtoFiber pro SCYb provides laser pulses with a center wavelength of 1030 nm and a duration below 100 fs. The turnkey system delivers typically 700 mW average output power making it the ideal laser source for specific applications in nonlinear microscopy or terahertz generation.

The new, all-fiber high-power laser system is based on a very stable, SAM mode-locked Er-doped oscillator operating at 1560 nm. The oscillator output is frequency-shifted towards 1030 nm using a nonlinear fiber. Yb-doped fiber amplifiers level up the power to typically 700 mW at the laser output. The system also includes a small grating compressor unit to achieve transform-limited output pulses of typically 90-100 fs, with more than 70 % of the total power in the main peak. It operates at a repetition rate of 80 MHz and provides a TEM00-beam shape with M2<1.2 and a beam diameter of 2 mm.

Toptica: FemtoFErb – the most compact and cost effective laser source for THz generation

TOPTICA’s new FemtoFErb is a turnkey laser system providing 100 mW average power at 1560 nm and a pulse duration of less than 150 fs at 100 MHz repetition rate. Using the same compact platform as TOPTICA’s PicoFYb, the FemtoFErb is a robust all-fiber setup based on Erbium doped fiber and saturable absorber mirror mode-locking (SAM) technology. The compact system includes all necessary control electronics and is equipped with a direct polarization maintaining fiber output interface. The FemtoFErb is an ideal solution for Time-Domain Terahertz generation or for metrology applications allowing highest accuracy laser-based distance measurements.

Also recently released: The new FemtoFiber pro UCP provides a super-continuum between 980 – 1400 nm and more than 30 mW output power. It shows pulse durations even below 25 fs, the fastest one can get on the market from a turnkey SAM modelocked fiber laser system. The system is ideally suited for biophotonics, pump-probe experiments or fs?spectroscopy. The UCP option expands TOPTICA’s successful FemtoFiber proseries and will be live demonstrated at the forthcoming Ultrafast Phenomena conference exhibition.
