  • What is Optical Parametric Amplification (OPA)?
    Article - 6 May 2014
    Optical parametric amplification (OPA) may be described as a process of amplifying an input signal in the presence of a higher-frequency pump wave. Apart from signal amplification, an idler wave is...
  • The Pockels Effect
    Article - 15 Aug 2013
    Pockels effect explains the influence of an electric field on a non-linear material in causing birefringence or altering the existing birefringence.
  • What is Optical Cross-Phase Modulation (XPM)?
    Article - 8 Oct 2013
    Optical cross phase modulation (XPM) may be described as a non-linear optical process where the wavelength of one light source affects the phase of another wave.
  • What is an Optical Fiber Isolator?
    Article - 22 Oct 2014
    Optical isolators are optical elements which allow light to propagate in only one direction. The propagation of light in one single direction is required in order to prevent optical back scattering or...
  • What is an Optical Amplifier?
    Article - 10 Jun 2013
    Optical amplifiers are devices that amplify an optical signal without converting it into an electric signal. Optical amplifiers are of two kinds: laser amplifiers and feedback amplifiers. Laser...
  • Gallium Indium Arsenic Antimony Lasers – Properties and Applications
    Article - 25 Apr 2014
    The gallium indium arsenic antimony lasers are diode lasers that emit infrared wavelengths. These laser diodes are important sources of lasers that generate wavelengths more than 2 µm.
  • Neodymium/Chromium Doped YAG (Nd/Cr:YAG) Lasers – Properties and Applications
    Article - 21 May 2013
    The YAG (yttrium aluminium garnet) laser is doped with chromium and neodymium in order to enhance the absorption characteristics of the laser. The NdCrYAG laser is a solid state laser.
  • Ytterbium YAG Lasers - Properties and Applications
    Article - 20 Jun 2013
    Ytterbium-doped yttrium aluminum garnet (Yb:YAG) laser is one of the most promising laser-active materials that are more suitable for diode-pumping than the traditional Nd-doped systems.
  • Rhodamine Dye Lasers - Properties and Applications
    Article - 15 May 2013
    Most of the commercially available dye lasers are either Fluorescein or Rhodamine laser dyes. Rhodamine dyes have efficient fluorescent characteristics, and can be detected using fluorometers.
  • Copper Vapor Lasers - Properties and Applications
    Article - 25 Apr 2014
    Copper vapor laser makes use of copper vapors as a lasing medium. It emits yellow and green laser light at 578.2 and 510.6 nm of the electromagnetic spectrum, respectively.
