FemtoFiber CARS

Flexible and Modular Femtosecond Lasers for CARS and SRS Applications

TOPTICA's FemtoFiber product line of ultrafast lasers is a flexible and modular platform that is ideally suited to form multi-branch laser systems. The individual lasers can be arranged in different combinations to cover the needs of various state-of-the-art microscopy and spectroscopy applications. These laser systems provide powerful phase-locked pulse trains, synchronized with attosecond precision, as well as broad wavelength tuning ranges, variable spectral widths and adjustable pulse durations. They enable demanding applications like label-free nonlinear microscopy or spectroscopy methods like CARS (Coherent Anti-Stokes Raman Spectroscopy) and SRS (Stimulated Raman Spectroscopy). Several popular configurations that cover the Raman fingerprint region and beyond are listed below. Other combinations or modified specifications are available on request.
