  • Liquid Cooling a Laser for System Optimization
    The performance of high-powered lasers depends on effective cooling. High-powered lasers generate a significant amount of heat that must be removed from the laser system to avoid overheating critical components. Carbon dioxide (CO2) lasers, excimer lasers, ion lasers, solid-state lasers, and dye
  • Laser Drilling Tablets for Use in Osmotic and Other Novel Drug Delivery Systems
    , many organics are transparent at the near infrared output wavelength (1.06 um) of industrial lasers based on Nd:YAG. Most organics also are strongly absorptive in the deep ultraviolet, and therefore could be processed using excimer lasers. However, the material removal mechanism in the ultraviolet
  • Medical Device Link . Laser-Manufactured Features in Medical Catheters and Angioplasty Devices
    . The principal, fundamental wavelengths of emission for these lasers are 10 um (CO ), 1 um (Nd:YAG), and 0.2 um (excimer). It is generally true that thermal considerations in the processing become more important with increasing laser wavelength, and penetration depths are generally greater, allowing
  • Liver On A Chip? Maybe Someday, Say Researchers
    channels and pores in the polymer scaffolds are micromachined using highly precise UV excimer lasers custom designed by The UV laser micromachining application was developed in JPSA's
  • MICRO: Ultrapure Gas Delivery - Karwacki (February 2001)
    in excimer lasers is critical to the industry. While the actual amount of fluorine fueling a laser is typically <0.2% by volume, it is usually delivered to the laser at concentrations between 1 and 5% and then diluted at the point of use by rare gases such as krypton or argon in neon. Although gas costs
  • Medical Device Link .
    A Class 1, fully enclosed system is in an excimer laser configuration. The IX-200 ChromAblate unit has a 238-nm wavelength that is suitable for micromachining of polymers, ceramics, and polyimides. An optional 193-nm beam-delivery package is also available, which is useful for materials that do
    Phoenix corporate research laboratories to demonstrate the capabilties of the Radiance process, a dry-cleaning technology that uses an excimer laser and a nonreactive gas to lift contaminants from wafers, FPD substrates, and photomasks. Built by Neuman MicroTechnologies
  • MICRO: Product Extras (June '2000)
    will provide service and spare parts for excimer lasers installed on ASML's steppers and scanners. Under a new agreement, ASML's customers can directly contact Cymer's field service engineers for laser-related service and spare parts. Information: 858/385-7139;, http://

  • LASIK (Laser in Situ Keratomileusis): Fundamentals, Surgical Techniques, and Complis
    A. LASIK: DEFINITION AND OVERVIEW Laser in-situ keratomileusis (LASIK) involves creating a corneal flap so that midstromal tissue can be ablated directly and reshaped with an excimer laser beam (1,2).
  • Management of Complications in Refractive Surgery
    The technique with the surgical correction of refraction, with the variant by Antonio Ruiz and others, stayed alive until the excimer laser appeared on the scene.

  • Lasers Based Manufacturing
    Chapters “ Excimer Laser Micromachining and Its Applications” and next six chapters present laser-based advanced technologies developed for manufacturing of micro-sized features such as channels.
  • Lasers in Dermatology and Medicine
    Modern diode lasers achieve higher powers than in the past, but their peak powers are still lag behind most pulsed solid- state lasers.14 Excimer lasers emit UV light and are used for photomodu- lation of the immune system.

  • Laser Processing and Chemistry
    Additionally, with UV lasers, in particular with excimer lasers and frequency-tripled or frequency-quadrupled Nd:YAG lasers, only moderate pulse energies are available.
  • Photorefractive keratectomy
    Photorefractive keratectomy (PRK) is the alteration of corneal curvature by photoablation with an excimer laser to eliminate or significantly reduce refractive errors.
