Buying Dispersion Compensation Modules

O/E Land's OEDCG-100 is a dispersion compensating module based on fiber Bragg gratings. It features a compact size, small insertion loss and customized dispersion slope. Our unique fiber grating apodization technology enables us to fabricate dispersion compensation grating filters with high isolation, low side lobes and low ripples.

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 APE femtoControl is a compact motorized dispersion compensation unit for optimization of the duration of femtosecond laser pulses in the spectral range of Ti:sapphire lasers.

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.
