Attenuation
Lesson Flashcards: The Properties of Laser Light Physics
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
