A laser produces a Gaussian beam because of the diffraction effect of the laser beam passing through an aperture. The electric field distribution of the beam follows a Gaussian shape due to the wave nature of light. This results in a beam that has a bell-shaped intensity profile with a narrower central peak and gradually decreasing intensity towards the edges.

the gaussian filter is also known as Gaussian smoothing and is the result of blurring an image by a Gaussian function.

The Gaussian distribution is the same as the normal distribution. Sometimes, "Gaussian" is used as in "Gaussian noise" and "Gaussian process." See related links, Interesting that Gauss did not first derive this distribution. That honor goes to de Moivre in 1773.

Because either there is a gaussian in the screen deflecting the beam or the sweep circuits in the TV are malfunctioning. The ticker tape shouldn't bend.
