FemtoFiber ultra FD

Femtosecond fiber laser with fiber delivery

Replacing the free-space paths between a Watt-level femtosecond fiber laser and a two-photon microscope setup is a total game-changer for modern multiphoton microscopy! Delivering femtosecond pulses directly from the laser source to the microscope through an optical fiber opens the door to completely new microscope designs for non-linear microscopy and makes laser safety and ease of use feel effortless – that's the power of fiber delivery.

In the FemtoFiber ultra FD, we combine a polarization-maintaining hollow-core fiber with our proprietary COOL technology: COOLAC offers hands-off, automated fiber coupling that eliminates manual alignment at installation, optimizes fiber coupling at the touch of a button, and monitors fiber coupling efficiency completely internally without the need for external tools or equipment. This means the fiber can stay connected to the microscope or user setup at all times.

An integrated AOM for fast power modulation, software-controlled dispersion precompensation, and our unique Clean Pulse Technology complete the system and ensure smooth, user-friendly performance.

No mirror alignment
Just automated fiber coupling. TOPTICA's COOL technology saves users time and effort with its automated fiber coupling (COOLAC).
Make misalignment an impossibility

A safeguard monitor regularly checks fiber coupling efficiency for best output performance. It all happens inside the laser. There is no need for external tools or equipment, such as power meters. This means the fiber can remain connected to the microscope at all times while the user can be sure of best performance each day.

Fast power control
An integrated acousto-optic modulator (AOM) enables fast power-modulation and flyback blanking in synchronization with the beam scanner. This minimizes sample damage and photo-bleaching. Also, a fast electronic trigger output is available as reference for TCSPC in FLIM and gated detection.
Main fluorophores addressed
The FemtoFiber ultra FD is ideally suited for the two-photon excitation of common fluorophores like GFP, GCaMP, RFP, mCherry, tdTomato, BFP, Alexa, NADH, FAD, auto-fluorescence or SHG-imaging.
More than 20 years of experience
TOPTICA is drawing upon 20 years of experience in developing OEM-class fiber lasers. We have tailored our FemtoFiber ultra series to provide our customers with an industrial-grade light engine for high-end applications. The reliable and compact laser design provides femtosecond pulses with high average power, excellent temporal and spatial beam quality.
