  • Using Critical Laser Scribing Processes for Solar Cell Manufacturing
    Article - 11 Sep 2015
    Solar cell manufacture is becoming a highly competitive field as high speed automation techniques tend towards zero defect tolerance. YAG lasers are being used for error-free scribing of solar panels.
  • Optical Dispersion - Principle and Applications
    Article - 15 May 2014
    Dispersion is the process of describing the characteristics of light waves and their interaction with a medium so that the group and phase velocities of the light propagating the medium depend on the...
  • An Introduction Doppler Cooling
    Article - 15 May 2014
    Doppler cooling is the laser based cooling of small particles, such as ions and atoms, which are trapped during the cooling process. It also involves the spontaneous emission of photons, which...
  • Cladding Modes - Definition and Applications
    Article - 15 May 2014
    Cladding modes are the regions or modes in optical fibers that are not restricted to the region around the core of the fiber. More specifically, cladding modes are regions in which the intensity of...
  • Pockels Cell - Definitions and Applications
    Article - 3 May 2014
    Pockels cell is an electro-optical device used for switching the direction of polarization of light beams. It is the primary component of various optical devices such as electro-optical modulators and...
  • Photodiodes - Their Working Principles and Applications
    Article - 29 May 2014
    A photodiode is a kind of light detector which involves conversion of light into voltage or current based on the mode of operation of the device. It consists of built-in lenses, optical filters, and...
  • Waveguide - Definition and Applications
    Article - 30 Apr 2014
    Waveguide is an optical structure which directs the electromagnetic waves of an optical spectrum. Some of the common types of waveguides include rectangular waveguides and optical fibers.
