  • Infrared Laser Marking Application
    Infrared (1064 nm) wavelength is arguably the most versatile of the marking wavelengths. IR lasers are capable of marking a wide variety of materials but are more commonly used on metals. A few of the best application materials include metals, plastics, and other materials.
  • Infrared Viewer Frequently Asked Questions
    Near-IR viewers are ideal for applications involving the alignment of infrared laser beams or of optical components in near-IR systems. Forensics & art restoration Substances have different transmission and reflection properties when viewed under near-infrared illumination as compared to visible
  • Advantages of Semiconductor Laser Diodes Versus Helium Neon Gas Lasers
    , and infrared, while HeNe lasers limit users to half a dozen or so wavelengths.
  • Laser Welding of Thermoplastics
    joining can not be a straight forward approach as each plastic has a very complicated absorption spectrum for the infrared laser beams and their weldability greatly depends upon the types of thermoplastics and also the type of laser to be deployed. This is so because the capacity to absorb heat
  • Volume Holographic Grating Wavelength Stabilized Laser Diodes
    The use of volume holographic gratings (VHGs) to stabilize lasers dates to the mid-1980s with 1.55 µm-semiconductor lasers. Accuwave Corporation followed by applying optical feedback to visible and near infrared lasers from 670 to 840 nm. However, at that time, lifetime issues with LiNbO3-based
  • Laser Drilling Tablets for Use in Osmotic and Other Novel Drug Delivery Systems
    By Frank Gaebler, Coherent, and Graham Coffee, Control Micro Systems The organic materials used in drug delivery systems nearly all display strong absorption in the infrared, so a carbon dioxide (CO ) laser, with nominal output at a wavelength of 10.6 um, is well matched for this task. In contrast
  • Sulfur Hexafluoride (SF6) Insulating Gas Leak Detection with an IR Imaging Camera
    the use of imagers that required active scanning with infrared lasers. The resulting systems were somewhat cumbersome and required specific conditions which limited their utility. Now there is an IR camera that can spot SF6 in very small amounts and is a completely passive system, requiring
  • The Thermal Diffusivity of Dentin Using Infrared Thermography (.pdf)
    The thermal diffusivity is one of the most important parameters when heat conduction is studied. The goal of this study is to obtain the thermal diffusivity of human teeth dentin after Er,Cr:YSGG laser irradiation using infrared thermography. Twenty one dentin slabs with 2 mm thickness were
