  • Beam Combining - Definition and Applications
    Article - 19 Jun 2014
    Beam combining is done through a number of processes in order to scale up the power and radiance of laser sources. There are a number of techniques that allow the built up of high power laser sources...
  • Population Inversion - Definition and References
    Article - 29 May 2014
    Population inversion is a condition of the laser medium where a system consisting of a group of molecules or atoms exists in a higher excited state with more quantum systems than that of the lower...
  • Plano-Convex Lens - Equation and Explanation
    Article - 29 May 2014
    A plano-convex lens is a convergent lens with one flat surface and one convex surface. It focuses parallel light rays to a positive focal point to form real images that can be manipulated using...
  • 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...
  • B-Integral - Definition and Significance
    Article - 15 May 2014
    B-Integral is defined as the measure of the non-linear phase shift of light in devices like amplifiers. B-Integral is a term that is specific to non-linear optics. The non-linear shift of the laser...
  • Gordon-Haus Jitter - Description and Principle
    Article - 15 May 2014
    The Gordon-Haus jitter is a timing jitter that originates from the fluctuations in center frequency. This jitter has been greatly influencing long haul fiber soliton systems by causing a jitter in the...
  • 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...
  • What is Super-Resolution Microscopy?
    Article - 6 May 2014
    Resolution limits owing to light diffraction have always been a major problem in analysing microscopic images.
  • Fizeau Interferometer - Definition and Applications
    Article - 1 May 2014
    Interferometric measurements can be carried out in an optical arrangement in which two or more beams originated from the same source, but passing in different paths are made to interfere....
  • Optical Cavity - Definition, Properties and Applications
    Article - 1 May 2014
    An optical cavity or an optical resonator may be described as an arrangement of mirrors that produce a standing light wave resonator.
