Where to Buy Pulse Compressors

The new few-cycle flexible hollow core fiber system allows you to choose various fiber lengths and inner diameters to achieve a desired nonlinear effect. Experimentally measured transmission for multi-mJ femtosecond pulses ranges between 50% and >90%, depending on the application.

The most versatile choice for laser pulse post compression: The few-cycle hollow core fiber supports input energies from 50 μJ to 100 mJ, up to 20 times compression and transmission >90% while keeping the footprint and optical path length at a minimum.

d-scan is an inline, compact and high-performance device for the simultaneous measurement and compression of even the most demanding ultrafast pulses. d-scan can be used either as a standalone system or integrated with existing optical pulse compressors. It handles broadband oscillators, amplifiers, OPAs and hollow-fiber compressors.

Coupling your beam into the d-scan is easily achieved in less than one minute and a full measurement takes less than 10 seconds. The resulting d-scan traces are very intuitive and a proprietary algorithm provides fast and accurate retrieval of the full electric field of the pulses.

Teraxion has the CM-V Chirped Module with VBG compressor matched pair, comprising a fiber pulse stretcher and a VBG pulse compressor.

We offer different add-on pulse compression modules (MIKSs) to spectrally broaden and temporally shorten the pulses from your picosecond or femtosecond laser. The modules are compatible with nearly all commercial ultrafast lasers. Pulse shortening factors of 5× to 10× are easily reachable in a single stage with over 90% transmission. The core of our technology is nonlinear spectral broadening in multipass cells. For example, MIKS1_S module shortens the input pulses with 200–400 fs pulse duration and 1–200 μJ energy down to <50 fs with extremely high transmission of over 90%. This module can be shipped to you and easily installed remotely.

Thorlabs manufactures a suite of options for dispersion management, including a pre-compensation module, dispersion compensating fiber, chirped mirrors, and low GDD optics. For ultrafast applications where dispersion must be well known and managed, Thorlabs’ portfolio includes a robust benchtop white light interferometer for characterizing reflective and transmissive dispersive properties of optics and coatings. The Chromatis™ dispersion measurement system covers 500 – 1650 nm, providing a means for measuring optics used for common femtosecond systems, including Ti:sapphire systems as well as 1 µm and 1550 nm oscillators. The Chromatis compliments our ultrafast family of lasers, amplifiers, and specialized optics including nonlinear crystals, chirped mirrors, low GDD mirrors/beamsplitters, and dispersion compensating fiber.

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.

The APE femtoControl is a compact motorized dispersion compensation unit for compressing femtosecond laser pulses in the spectral range of Ti:sapphire lasers, as well as for 2P and 3P microscopy (options for e.g. 1300 nm, 1700 nm, and up to 2500 nm possible.

femtoControl compensates for material dispersion by applying the inverse amount of dispersion to the pulse. This is generated by a pair of prisms on motorized translation stages allowing continuous adjustment of the pulse length.

For example, femtoControl can help to achieve more crisp and clearer microscope images especially for multi-photon microscopy.
