Immersion Lens Focuses Radially Polarized Beam for Laser Nanoprocessing
Immersion Lens Focuses Radially Polarized Beam for Laser Nanoprocessing

A research team at Tohoku University investigated the use of radially polarized laser beams, also known as vector beams, to enhance processing accuracy and resolution in ultrafast laser processing. A radially polarized beam generates a longitudinal electric field at the focus spot. Compared to conventional beams with linear or circular polarization, a radially polarized beam produces a small focal spot, especially when it is tightly focused using a high-NA lens.  Read Article

Mass-Production Method Aims to Drive Metalenses Toward Widespread Commercial Use

To support the mass production of metalenses for use in applications like lidar and miniature medical devices, researchers at Pohang University of Science and Technology (POSTECH) and Korea University collaborated to develop two methods for the scalable, wafer-scale manufacture of metalenses operating in the NIR region. The techniques devised by the team could reduce the cost of metalens production by as much as 1000×.  Read Article

Optical Filters: Application and Design Considerations
Optical Filters: Application and Design Considerations

Tue, Apr 23, 2024 1:00 PM - 2:00 PM EDT
Optical filters can discretely transmit or reject specific wavelengths or ranges of wavelengths of light. Utilizing this capability in photonics-based instruments creates the need for a better understanding of optical filter design considerations and how specifications influence performance and cost. Craig Hanson of MKS/Newport discusses the fundamental principles of optical coatings and filter types and explains the significance of filter parameters and the benefits of design review. He also explores accessory options and subsystem integration. Next Hanson unveils MKS’s unique manufacturing processes and capabilities for custom optical filters from prototype to high-volume production. Finally, this presentation concludes with an open Q&A, for which Hanson is joined by Mark Roberts, principal thin-film engineer at Newport. Presented by MKS Newport.
