  • Laser Welding Plastics Using a Fiber Laser
    , or a. How laser welding of plastic works (IR. Fiber Laser. wavelength): In this process, the two layers, to be joined,. Quasi Simultaneous Welding. must differ in such a way that the top one allows. Two scanner mirrors deflect the laser spot and. the infrared light to pass through while the. guide
  • Laser Trackers
    measurement over incremental. distance measurement is the ability simply to point the beam at the. target and shoot. The ADM system measures the distance to the target. automatically, even if the beam has previously been broken. In a tracker. with ADM, infrared light from a semiconductor laser reflects off
  • Phase Conjugate Laser Optics - Preface
    Since the discovery of the laser in the 1960s, a great amount. of research activity has led to an impressive increase of the overall. performances of the sources emitting in the visible or in the infrared. spectral regions. The most significant achievements for solid-state. lasers in the last 10
  • Laser Welding Carbon Nanocomposites
    . In the current study, direct diode and Nd:YAG solidstate lasers were used to transmission weld -carbon nanocomposite materials. The experimentation was focused on exploiting the infrared absorbing characteristics of the carbon nanocomposites. Polyetheretherketone (PEEK) based polymer was used
  • How a helium neon gas laser works
    The Helium Neon laser is one of the most economical and commonly used gas lasers on the market. The. laser is typically designed to operate in the red at 632.8nm, although many users find it beneficial in the. green at 543.5nm, yellow at 594.1nm, orange at 611.9nm, and in the infrared at 1523
  • Near Infrared ( NIR ) Applications with Miniature Fiber Optic Spectrometers
    applications which. wavefront on the detector array, providing a uniform. occur in the Near Infra-Red (NIR) 900-2200nm range,. 1 nm resolution across the wavelength range 190-. which use InGaAs Photo Diode Arrays (PDAs). 900 nm (using a 25 µm slit). The improved focus. instead of CCDs. The InGaAs PDAs
  • Workstation for Laser Direct-Write Processing (.pdf)
    the most uses thus far are infrared CO. easily be fabricated without the use of sacrificial layers. 2 gas lasers,. ultraviolet excimer gas lasers, and visible solid-state lasers. Finally, the carbon based nature of the photosensitive. When interacting with these kinds of lasers, materials absorb
  • Power Stabilization of the Dual-Mode Laser Using Volume Holographic Gratings (.pdf)
    from. two infrared lasers on a suitable photomixer is currently dis-. Fig. 1. Reflective volume holographic grating (VHG): the diffracted wave-. length that matches the Bragg condition is reflected to the same side of the. cussed often in the literature [1]–[3]. Such frequency sources. grating
