  • 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.
  • High Performance Fibre-Optic Infrared Temperature Sensors
    News - 13 Sep 2007
    The Convir FL series of fibre-optic infrared temperature sensors has now grown with the addition of three new models. These new sensors extend the temperature range of the FL series enabling them to...
  • What are Optical Flats?
    Article - 6 May 2014
    Optical flats can be described as an optical grade glass which is polished and made extremely flat on both surfaces, used for determining the flatness of various optical surfaces.
  • 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...
  • Indium Gallium Nitride (InGaN) Lasers – Properties and Applications
    Article - 11 Jul 2013
    Indium Gallium Nitride (InGaN) laser is a semiconductor laser. It is also called blue laser as the emitted wavelength of light is perceived as blue colour by the human eye. InGaN is essentially a...
  • Alexandrite Lasers – Properties and Applications
    Article - 5 Jun 2013
    Chromium doped chrysoberyl lasers are called alexandrite lasers. The synthetic alexandrite crystal is grown from the chrysoberyl mineral by the floating zone method.
  • Helium Selenium Laser – Properties and Applications
    Article - 29 Aug 2013
    Helium selenium laser falls into the category of metal-vapour lasers. The operation mode of this laser is similar to that of the helium cadmium laser. Spontaneous emission occurs when selenium...
