Date Announced: 28 Jul 2011
Workshop of Photonics (WOP) together with prof. Peter G. Kazansky’s group from Optoelectronics Research Centre (ORC) at the University of Southampton developed a direct laser writing technique for the production of radial polarization converters also known as Z polarizers.
Such radial polarizers would be mainly applied at laser machining, microscopy, optical tweezers as well as Raman spectroscopy systems. Our Z polarizers have distinguishing features: they are resistant against high-power laser radiation due to monolithic fused silica window design; anti-reflection (AR) coatings can be applied; and a single element is used both for polarization conversion and generation of higher topological charge optical vortices.
WOP's and ORC's laboratories expect to prove significant advantages of Z polarizers in laser micromachining, such as decreased spot size and uniformity of light-material interaction regardless of machining direction.
Being a commercialization partner Workshop of Photonics is also looking for integrators and end-users in the fields of laser machining, microscopy and optical tweezers. Testing units are already available, while small scale production of the Z polarizer devices is planned for the middle of autumn. Custom development of machining heads and optical assemblies incorporating radial polarizers is possible upon request.
The University of Southampton has already applied for a patent application and has appointed Altechna R&D Ltd. an exclusive commercialization partner.
