Femtosecond laser mirrors

Acal BFi, the European leader in advanced technology solutions, have launched a new range of ultra-high performance femtosecond laser mirrors to the market.

Providing an unrivalled combination of ultra-broad spectral bandwidth (> 200nm), superior reflectivity (> 99.5% on 120nm, and > 99% on the entire 200nm), high damage threshold from femtosecond to nanosecond regime and low GDD (< 20fs² on 120nm, and < 60 fs² on the entire 200nm), Acal BFi’s high performance laser mirrors are specially designed to meet the needs of users and designers of ultra-short femtosecond lasers.

Jean-Claude Sanudo, Photonics Business Unit Director of Acal BFi comments:
"The launch of the MLD and MMLD range of femtosecond laser mirrors to the market marks the successful start of Acal BFi’s own-brand range of optics.  It is testament to our team’s hard-work that this range is of such high quality and has positioned us at the leading-edge of the photonics market”.

The MLD and MMLD range benefits from a unique coating technology, developed for the most challenging ultrafast laser developments, and tested and qualified by well known research institutes. The mirrors can be used in both S polarization and also in P polarization, allowing innovative system configuration and therefore simplifying the design chain.

While the most common optics, which are flat mirrors of one and two inches, are available from stock, Acal BFi’s components are also available in sizes up to 40 inches and/or with non-flat surfaces, including 90° off-axis parabola which is ideal for compressors. Coatings are available for both the Ti:Sa users and 1030 nm laser users, while other central wavelengths can be designed on request.
