Multiflex – Making Ultrafast Lasers faster
Ultrafast lasers with pulse durations down to the femtosecond range are known for their ultra-precise ablation and cutting results, but also for their long process durations. Funded by the EU, the MultiFlex project aims to make material processing with ultrafast lasers up to a hundred times faster by using a high-power USP laser with more than 1kW average power and a selective multibeam approach to deliver the power efficiently to the workpiece. Several partners are involved in this project including AA Opto Electronic.
AA’s Contribution
AA Opto Electronic is quite proud to make its contribution to this project, by developing and designing a high optical power Acousto Optic Modulator (AOM) together with the associated RF driver. The AOM here is a multi-channel one capable of handling up to 8 beams simultaneously and switching them ON/OFF individually with rise/fall time < 200 ns. Thanks to our RF electronics experience, we have also developed the associated RF driver based on synthesizers with 8 outputs. With this complete set, AA will certainly help to reduce the overall process time required for this project. Watch the video here

3 colors are entering simultaneouly the AOD (Blue, Red, Green). A Multi-Color-Machine (MCM) from Pegasus Optik GmbH is used with operating wavelengths 635nm, 520nm and 488nm (more info about MCM). The full frequency range of the AOD is swept in a raster scan mode.
For most of the applications, the overlap part of the deflection is used. For narrow wavelength bands, the overlap is very high.
We can get similar ovelaps for Infrared wavelengths.

About AA Opto Electronic
AA OPTO-ELECTRONIC proposes one of the most complete range of standard Acousto-optic components and associated Radio frequency drivers. AO devices cover wavelengths from 180 nm to 11 µm. These products are available for rapid delivery in any quantity. In case you do not find a product which follows your need, then we will be pleased to study a custom device.
The range of RF drivers cover from DC to 3 GHz and up to 500 W. These drivers are matched to AO devices. AA also propose a large range of customized electronics as well as microwave passive components and broadband power amplifiers up to 50 GHz, 1 KW.
AA was founded in 1979, under the name «Automates et Automatismes». It became a limited company in 1988 under the new name of AA Sa, specialising in acousto-optic components and their associated RF drivers. AA is a world leader in the manufacturing of quality Acousto-optic and radio frequency devices. Close collaboration with universities and research institutes, provided invaluable knowledge and experience in the design and manufacturing processes of Acousto-optic devices and radio-frequency sources. Continuous R&D keeps pace with advances in laser and electronic technology to ensure AA continues to offer state-of-the-arts products. AA offers its customers solutions from prototype design to large volume manufacturing thanks to its internal resources and In-house capabilities. Our Headquarter is located in ORSAY, near Paris in France. This is also our optical manufacturing center. All RF drivers are manufactured in our St Avertin plant, located 200 kms south of Paris.
