Simplifying multi-photon microscopy with stress-less femtosecond lasers
FemtoFiber ultra 1050
Femtosecond fiber laser
For the best image brightness in multiphoton microscopy, you need short pulses, high power and, most importantly, a clean temporal pulse shape – and that's where we come in!
The FemtoFiber ultra 1050 is a femtosecond fiber laser that delivers outstanding peak power for two-photon microscopy, while keeping unwanted heating of the sample low.
Additionally, the system is incredibly user-friendly thanks to its software-controlled dispersion precompensation (GDD) and integrated AOM for power modulation.
Our robust and reliable fiber laser technology is the key to lowering the cost of ownership of your laser systems.
The FemtoFiber ultra 1050 is absolutely perfect for the multiphoton excitation of common fluorophores like mCherry, Propidium Iodide, tdTomato, eYFP, DsRed, mRFP, or mOrange.

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.
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
High peak power and clean pulse shape are needed for deep-tissue imaging.
Two-Photon microscopy
Two-photon excitation microscopy opens a window deep into living tissue.
Semicon inspection & metrology
Laser-based metrology and inspection have become indispensable tools for shrinking feature sizes, more and thinner layers, as well as increasing chip and package areas.
Two photon polymerization (3D microprinting)
TOPTICA’s ultrafast laser platforms provide the pulse duration, repetition rate, and spatial coherence essential for high throughput and ultimate structural fidelity in 3D laser lithography.
Label free & clinical imaging
Label-free imaging visualizes chemical and structural information in living cells without stains or labels.
Options
AOM
An AOM for fast modulation of the laser light can be integrated into the system. Ready to use. No complicated optics taking up valuable table space.
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. Our product FemtoFiber ultra FD delivers its pulses via a polarization-maintaining hollow-core fiber.
