Lesson Flashcards: The Properties of Laser Light Physics

Attenuation

The decrease in the intensity of a beam over the distance that the beam travels

Scattering

Parts of a beam reflecting from objects in the path of the beam in directions other than the direction of the beam

Coherent light

Light consisting of waves with equal wavelength that are in phase

Monochromatic light

Light consisting of waves with equal wavelength

Spectral width

The range of the wavelengths in an electromagnetic spectrum with intensities equal to or greater than a set fraction of the peak intensity wavelength

Collimation

The property of a beam of light that is neither diverging nor converging
