ProductEncDescription
anti-reflection coatings E

UltraFast Innovations (UFI) offers broadband anti-reflection coatings which are suitable for ultrafast laser devices. Versions for different wavelength ranges and angles of incidence are available.

autocorrelators Eautocorrelators from UltraFast Innovations

The TUNDRA third-order autocorrelator serves as a highly sensitive diagnostic tool for laser pulse contrast measurements. Its dynamic range reaches up to 14 orders of magnitude, sufficient for detecting even 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. Available wavelengths are 800 nm and 1030 nm; others can be provided on request. Using third-harmonic generation, our autocorrelator can distinguish between pre- and post-pulses.

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

beam splitters E

UltraFast Innovations (UFI) offers various beamsplitters which are suitable for broadband ultrashort pulses: they offer 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 mirrors Echirped mirrors from UltraFast Innovations

UltraFast Innovations (UFI) has ultra-broadband compression mirror sets which are available in many configurations. For example, mirror sets for pulse compression in chirped-pulse Ti:sapphire amplifier systems, broadband oscillators and other applications cover the wavelength range of 400–1200 nm, i.e., up to 1.5 octaves. 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 UltraFast Innovations (UFI).

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

optical filters E

UltraFast Innovations (UFI) offers 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 in time, resulting in the generation of sub-optical-cycle pulses. Based on that technology, we also offer the first commercial light field synthesizer.

pulse compressors Epulse compressors from UltraFast Innovations

The Savanna-HP pulse compressor is based on a stretched flexible hollow-core fiber (SF-HCF). It has been developed in a 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.

reflectometers Ereflectometers from UltraFast Innovations

Our GLACIER reflectometer utilizes the extreme sensitivity of cavity ring-down spectroscopy for quantifying the losses of advanced optical coatings down to the level of 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.

The GLACIER-C is another cavity-ringdown reflectometer, based on a supercontinuum light source and a tunable monochromator. This allow for a freely selectable wavelength within 450 nm and 2000 nm and thus offers an unprecedented flexibility as it is not limited to available diode laser wavelengths.
