Laser Beams – Gaussian, coherence, beam quality,
Laser beams are light beams propagating dominantly in one direction, i.e., with low beam divergence. This is possible due to the high spatial coherence.
Why do most laser beams have a Gaussian intensity profile?
Gaussian beams fall naturally out of the solutions to optical propagation in homogeneous media (see, e.g., Yariv''s Quantum Electroncs). Since most laser cavities can be modeled reasonably
