FemtoFiber ultra 1050

Femtosecond fiber laser
In two-photon microscopy, peak-power is brightness! If you care for the best image brightness, you need short pulses, high power, and most importantly a clean temporal pulse shape. The FemtoFiber ultra 1050 features the highest peak power available on the market and hence enables unmatched image brightness.
Additionally, software-controlled dispersion precompensation (GDD) and an integrated AOM for power modulation, make the system extremely user-friendly.
TOPTICA's robust & reliable fiber laser technology significantly reduces the cost of ownership of your laser systems.
The FemtoFiber ultra 1050 is ideally suited for the two-photon excitation of common fluorophores like mCherry, Propidium Iodide, tdTomato, eYFP, DsRed, mRFP or mOrange.

Your Benefits

Compact & Low cost of ownership
Saving table space with all-integrated robust fiber laser system.
Clean Pulse Technology
TOPTICA’s unique Clean Pulse Technology provides clean, pedestal-free pulses even after the fiber for best image brightness.

User-friendly GDD
Short pulses and software-controlled dispersion precompensation (GDD) for user-friendly handling TOPTICA’s FemtoFiber ultra provides motorized group delay dispersion (GDD) pre-compensation that can be controlled in software.  Due to chromatic dispersion, a femtosecond pulse stretches in time when transmitted through optical material in the microscope. GDD pre-compensation adds the opposite dispersion to circumvent this effect by cancelling it out. TOPTICA’s software-controllable GDD pre-compensation ensures short pulses at the sample plane with user-friendly, repeatable optimization of fluorescence signal strength via the graphical user-interface (GUI).
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.
For all important fluorophores
The FemtoFiber ultra 1050 is ideally suited for the two-photon excitation of common fluorophores like RFP, mCherry, Propidium Iodide, tdTomato, eYFP, DsRed, mOrange, auto-fluorescence or SHG-imaging.

Applications

Neuroscience
Two-Photon microscopy
Semicon inspection & metrology
Two photon polymerization (3D microprinting)
Label free & clinical imaging

Options

AOM
An AOM for fast modulation of the laser light is integrated into the system.
Pulse picker
An integrated pulse picker reduces the effective repetition rate from 80 MHz to 8 MHz (1:10).
Custom repetition rate
The custom repetition rate provides a modified oscillator with a pre-defined repetition rate between 40 and 80 MHz upon ordering.
Dual-color
With the FemtoFiber ultra dual-color option two FemtoFiber ultra are optically synchronized and allow simultaneous imaging with two different laser colors. No laser wavelength tuning is required.
FemtoFiber ultra 525
The system has an additional SHG unit that can generate femtosecond pulses with an average power of > 0.5 or > 1 W at 525 nm.
Fiber delivery
Replace the free-space path between the femtosecond laser and the two-photon microscope. The FemtoFiber ultra FD or Mini2P variant delivers its pulses via a polarization-maintaining hollow-core fiber.
