I seem to remember seeing somewhere that lightsabers are actually not lasers but rather plasma held in that shape by some sort of force field. I think it should be in the explanation if it is true.

Most of "scientific" explanations of lightsaber (and blaster bolts) says about plasma contained in magnetic field. For example check this SE Endless "laser sword" pun was also used in, without Luke but with massive hull breach. 06:38, 13 October 2014 (UTC)PTwr

One joking "explanation" of the light sabre conjured long ago on a newsgroup I was on had used the Fourier analysis. It proposed that the "handle" emits multiple beams of light with very well defined frequencies and amplitudes, corresponding to a Fourier series for a pulse wave with a low duty cycle - so the waveforms emitted cancel themselves after a short distance. The joke went on, saying that since the sum of the Fourier series is periodic, someone practicing the sabre on the Earth can accidentally chop off the head of someone walking on the Moon. 07:26, 13 October 2014 (UTC)
