WebFor diffraction-limited beams, the Rayleigh Range ZR is determined by its waist radius R0 and laser wavelength λ (ZR = π·(R0)²/λ). For example, the Rayleigh Range of a Gaussian beam is the distance from the beam waist (in the propagation direction) where the beam radius is increased by a factor of √2 (which WebA diffraction-limited beam (e.g., a Gaussian) is one for which this product is equal to the smallest value allowed by the uncertainty principle. Share. ... If your chief ray angle is zero, that means your beam came from a source of zero size. From radiometry we know that would require a source of infinite radiant exitance. Outside that ...

http://aml.engineering.columbia.edu/ntm/level2/ch02/html/l2c02s07.html The effects of diffraction are often seen in everyday life. The most striking examples of diffraction are those that involve light; for example, the closely spaced tracks on a CD or DVD act as a diffraction grating to form the familiar rainbow pattern seen when looking at a disc. This principle can be extended to engineer a grating with a structure such that it will produce any diffraction pattern desired; the hologram on a credit card is an example.
