SUMMARY

Solitons are solitary waves that maintain their shape over long distances without dissipating, as exemplified by light waves in optical fibers and certain conditions in Bose-Einstein condensates. Regular light waves do not qualify as solitons because they decay according to the inverse square law (1/r²) when emitted as a spherical pulse. However, well-focused laser pulses can be classified as solitons under specific conditions due to their ability to maintain shape and coherence over distance.

PREREQUISITES
  • Understanding of wave dynamics and soliton theory
  • Familiarity with optical fibers and their properties
  • Knowledge of laser technology and pulse formation
  • Basic principles of Bose-Einstein condensates
NEXT STEPS
  • Research the properties of solitons in nonlinear optics
  • Explore the behavior of light in optical fibers
  • Study the formation and characteristics of laser pulses
  • Investigate the applications of solitons in quantum mechanics and B.E. condensates
USEFUL FOR

Physicists, optical engineers, and researchers in nonlinear optics and quantum mechanics will benefit from this discussion, particularly those interested in the behavior of light and wave phenomena.

"Solitary waves that run a long distance without losing their shape or dying out are a special class of waves called solitons."

Such examples as in light waves in optical fibers, vibration frequencies within crystalline structures, and B.E. condensates.

My question is does regular light wave count as a soliton? Does light ever slow down or run out so to speak?

If you emit a spherical pulse of light it will decay as 1/r² so it will decay and not be a soliton. You might count a well-focused laser pulse as a soliton.
