02 Aug 2011 Workshop of Photonics together with prof. Peter G. Kazansky group from Optoelectronics Research Centre of Southampton University developed a direct laser writing technique for production of radial polarization converters also called as Z polarizer, Z-plate or q-plate.
Primary applications for such radial polarizers are in laser machining, microscopy and optical tweezers as well as Raman spectroscopy systems. Unique features of this converter are that it is made in the volume of monolytic fused silica window, therefore resistant against high power laser radiation; AR coatings might be applied; and a single element is used both for polarization conversion and generation of optical vortices.
Significant advantages, such as decreased spot size and uniformity of light-material interaction regardless of machining direction are being prooved in WOP's and ORC's laboratories.
Workshop of Photonics as the commercializing partner 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 Z polarizer devices is planned for the middle of autumn.
Southampton University applied for patent application and appointed exclusivity in commercialising activities for Altechna R&D Ltd. Custom development of machining heads and optical assemblies incorporating the radial polarizer is possible on request. |
