  • Gouy Phase-Shift - Explanation and Principle
    Article - 15 May 2014
    The Gouy phase shift is a popular axial phase shift that occurs in a converging light wave when it passes through its focus in propagating from -‡ to +‡ . The Gouy phase shift is an additional phase...
  • 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...
  • Superpulse Lasers - Definition and Applications
    Article - 19 Jun 2014
    Superpulse is a specific waveform commonly used in CO2 laser systems either in a pulsed or continuous pattern. Superpulsed lasers are capable of emitting several thousand bursts of power per second.
  • Radiance - Deinition and Introduction
    Article - 19 Jun 2014
