Product categoryEncDescription
anti-reflection coatingsS E

UltraFast Innovations (UFI) offers broadband anti-reflection coatings suitable for ultrafast laser devices, with numerous options for different wavelength ranges and angles of incidence.

autocorrelatorsS Eautocorrelators from UltraFast Innovations

TUNDRA®, by UltraFast Innovations (UFI®), is a third-order autocorrelator, which serves as a highly sensitive diagnostic tool for laser pulse contrast measurements. Using third-harmonic generation, TUNDRA can distinguish between pre- and post-pulses. Its dynamic range reaches up to 14 orders of magnitude, sufficient for detecting even the tiniest parasitic pre- and post-pulses. The scan range is up to 3.8 ns, and pulse durations from <20 fs to 3 ps can be measured. It is available for 800 nm and 1030 nm but other wavelengths can be provided upon request.

TUNDRA is a fully automated device, serving as an invaluable tool for state-of-the-art characterization of ultrashort laser pulses. Its designed ensures that ghost pre/post pulses are avoided.

beam splittersS Ebeam splitters from UltraFast Innovations

UltraFast Innovations (UFI®) manufactures various beamsplitters suitable for broadband ultrashort pulses: they provide consistent performance over a broad bandwidth and low group delay dispersion (GDD). Versions for different wavelengths, splitting ratios, and angles of incidence are available.

chirped mirrorsS Echirped mirrors from UltraFast Innovations

UltraFast Innovations (UFI®) provides a variety of ultra-broadband compression mirror sets in several configurations. For example, mirror sets for pulse compression in chirped-pulse titanium:sapphire amplifier systems, broadband oscillators, and other applications cover the wavelength range of 400–1200 nm, i.e., up to 1.5 octaves. Our customers have reached pulse durations around 3 fs after spectral broadening in hollow-core fibers and gas cells in combination with our mirrors.

Such mirrors are not only optimized for a broad reflection bandwidth, but also for a precise chromatic dispersion profile with low group delay dispersion (GDD) fluctuations. In some cases, we use two mirrors with different angles of incidence to further reduce the oscillations (double-angle technology).

custom opticsS Ecustom optics from UltraFast Innovations

UltraFast Innovations (UFI®) offers numerous types of optical elements in customized forms – for example, ultrafast low-dispersion or dispersive mirrors, ultrahigh reflection mirrors, input and output coupler mirrors, spectral filters, and mirrors for the extreme ultraviolet (XUV) and soft X-rays.

dichroic mirrorsS Edichroic mirrors from UltraFast Innovations

UltraFast Innovations (UFI®) provides a wide range of laser mirrors, including dichroic mirrors e.g., for input and output coupling in ultrafast laser systems. In addition, these dichroic mirrors can be used for building a so-called wave synthesizer. Based on that technology, we have developed the first commercial light field synthesizer.

dispersive mirrorsS Edispersive mirrors from UltraFast Innovations

UltraFast Innovations (UFI®) provides a wide range of ultra-broadband compression mirror sets in various configurations. For example, mirror sets for pulse compression in chirped-pulse titanium:sapphire amplifier systems, broadband oscillators and other applications cover the wavelength range between 400–1200 nm, i.e., up to 1.5 octaves. Our customers have reached pulse durations around 3 fs after spectral broadening in hollow-core fibers and gas cells in combination with mirrors designed and manufactured by UFI. In addition, we also offer large dispersive optics with up to 200 mm diameter.

Such mirrors are not only optimized for a broad reflection bandwidth, but also for a precise chromatic dispersion profile with low group delay dispersion (GDD) fluctuations.

UltraFast Innovations (UFI®) offers passive enhancement cavities to achieve effective nonlinear conversion even in extreme spectral regions. Typical applications include XUV generation via higher harmonic generation in a gas at megahertz pulse repetition rates and hard X-ray generation via Thomson (inverse Compton) scattering of relativistic electrons. The cavities also provide longitudinal and transverse mode filtering and can be used for the highly precise characterization of laser optics concerning amplitude and phase.

One can generate isolated attosecond pulses through HHG by injecting suitable femtosecond laser pulses.

The optical breadboard inside the chamber is isolated from environmental vibrations for optimum temporal and pointing stability. A feedthrough with a noble gas inlet is included to supply e.g., argon, neon or helium for HHG in the spectral region of interest.

For example, we provide mirrors for thulium- and holmium-based systems operating in the 2-μm spectral region, Cr:ZnS systems around 2.4 μm and Cr:ZnSe for 3.2 μm. Such mirrors can be provided with precise control of chromatic dispersion.

K2, by UltraFast Innovations (UFI®), is a pulse delay unit specially designed for the extreme ultraviolet (XUV) and soft X-ray region, where particularly high precision and stability are required. A two-segment mirror sends IR pulses and lower divergent XUV/soft X-ray pulses to a common focus with an interferometrically adjustable precise time delay. This allows temporally resolved experiments with pumping systems of interest either with the XUV/soft X-ray pulse and probe it with the IR or vice-versa. Based on the nature of e.g., attosecond pulses generated in the XUV/soft X-ray range by high harmonic generation (HHG), this offers state-of-the-art highest temporal resolution for your experiments.

optical filtersS E

UltraFast Innovations (UFI®) provides spectral filters for ultrashort pulse applications – for example, for preserving the pulse duration of reflected or transmitted pulses.

By using such spectral filters, researchers from Prof. Krausz’s group were able to build a so-called wave synthesizer. We were able to split or combine radiation from 250 to 1100 nm in four channels: 250–290, 290–350, 350–500, and 500–1100 nm. The phases of reflection and transmission are controlled. This allows one to precisely combine radiation from four channels, both spatially and temporally, resulting in the generation of sub-optical-cycle pulses. Based on that technology, we have developed the first commercial light field synthesizer.

pulse compressorsS Epulse compressors from UltraFast Innovations

SAVANNA-HP, by UltraFast Innovations (UFI®), is a pulse compressor based on a stretched-flexible hollow-core fiber (SF-HCF). It has been developed in collaboration with the Institute for Nanophotonics in Göttingen. It spectrally broadens high-energy femtosecond input pulses by nonlinear interaction with a noble gas of adjustable gas pressure inside a hollow fiber and subsequently compresses the pulse using chirped mirror technology from UltraFast Innovations (UFI).

The state-of-the-art SF-HCF technique allows nearly ideal waveguiding, reducing the losses to a minimum and allowing the application of self-phase modulation over an interaction length of up to 8 m. It can handle extremely intense input pulses with a few tens of mJ pulses and an average power of up to 20 W – with active cooling, even up to several hundred watts. With this, we provide an unmatched compression unit for today's state-of-the-art lasers.

GLACIER®, by UltraFast Innovations (UFI®), is a reflectometer that utilizes the extreme sensitivity of cavity ring-down spectroscopy to quantify the losses of advanced optical coatings down to 5 ppm. As a typical application, the device can be used for characterizing supermirrors with up to 99.9995% reflectivity. It is delivered with a computer and a user-friendly software interface for acquisition and real-time analysis.

GLACIER-C is another cavity-ringdown reflectometer, based on a supercontinuum light source and a tunable monochromator. This allows to select any wavelength between 450 nm and 2000 nm, offering unprecedented flexibility as it is not limited to available diode laser wavelengths.
