Smarter Way to Make UV Beams

Facebook X LinkedIn Email
ANN ARBOR, Mich., Nov. 30, 2011 — A better way to build compact ultraviolet (UV) light sources with low power consumption has been discovered using an optimized optical resonator, which could lead to improved information storage, microscopy and chemical analysis. Researchers at the University of Michigan used a whispering gallery resonator to take an infrared signal from relatively cheap telecommunication-compatible lasers and, using a low-power, nonlinear process, boosted it to a higher-energy UV beam. In the setup for this experiment, a telecommunication-compatible infrared beam is coupled to the...Read full article

    lithography
    Lithography is a key process used in microfabrication and semiconductor manufacturing to create intricate patterns on the surface of substrates, typically silicon wafers. It involves the transfer of a desired pattern onto a photosensitive material called a resist, which is coated onto the substrate. The resist is then selectively exposed to light or other radiation using a mask or reticle that contains the pattern of interest. The lithography process can be broadly categorized into several...
