High power UV excimer laser mirrors for 45° AOI ; ArF (193 nm), KrF (248 nm), or XeCl (308 nm). After the discovery of excimer lasers in 1982, lamp-based lithography techniques became obsolete. These high quality excimer laser mirrors provide high reflectivity, high surface accuracy and quality, and high laser damage threshold for the UV operating wavelengths of ArF, KrF, and XeCl lasers. The excimer laser was invented in 1970 by Nikolai Basov, V. A. Danilychev and Yu. Like most gas lasers, excimer laser power is provided by an electrical current source. These lasers generate the light that photolithography scanners use to image patterns on silicon wafers. Current state-of-the-art lithography tools use deep ultraviolet (DUV) light from the KrF and ArF excimer lasers with wavelengths of 248 and 193 nanometers (the dominant lithography technology today is thus also called "excimer laser lithography" ), which has enabled transistor feature sizes to shrink to 7 nanometers (see below). Applications of krypton fluoride laser are mainly in deep-ultraviolet photolithography. For the best experience on our site, be sure to turn on Javascript in your browser. The krypton fluoride (KrF) laser is an excimer laser, which emits deep ultraviolet wavelengths. Laser Optics 248nm KrF Excimer Viewports $ 730.00 – $ 1,308.00 DUV Grade (Laser) Fused Silica Viewport w/ V-Coat 248nm R < 0.25% Per Surface, 1.40″ View Diameter, 2.75″ Conflat Flange This technological breakthrough leads to dramatically less cost to run your laser. M. Popov, at the Lebedev Physical Institute in Moscow, using a xenon dimer (Xe2) excited by an electron beam to give stimulated emission at 172 nm wavelength. The term excimer is the short form of excited dimer means a molecule formed by combining two identical noble gas (i.e. Further wavelengths are available on request. Surface inspection for defects on the shop floor can be achieved with the 4D InSpec surface gauge. CVI Laser Optics is An IDEX Optical Technologies Solution. The EX10 excimer laser offers state of the art performance in a compact package and provides a highly reliable, powerful source of ultraviolet radiation. Copyright © 2020 CVI Laser, LLC. Commonly used excimer lasers are krypton fluoride, argon fluoride, xenon fluoride, and xenon chloride.

Custom mirrors are available upon request. [12] Pulse repetition rate. Lambda's 600K device delivers high power, 180 W, stabilized output energy of 600mJ at 300 Hz. It consists of two elements, krypton and fluorine, as the lasing medium. Excimer lasers, such as XeF and KrF, can also be made slightly tunable using a variety of prism and grating intracavity arrangements. High quality mirror substrates, windows and lenses of CaF2 (248 nm excimer grade or UV quality, HELLMA Materials GmbH). These high quality excimer laser mirrors provide high reflectivity, high surface accuracy and quality, and high laser damage threshold for the UV operating wavelengths of ArF, KrF, and XeCl lasers.
