SUMMARY
Laser light is produced through stimulated emission, resulting in coherent photons that maintain the same phase. This coherence prevents the formation of alternating bright and dark light patterns, as interference requires waves with differing phases. The width of the laser medium influences beam collimation, introducing diffractive effects that affect the transverse modes of the beam. Consequently, the smooth edges of these modes eliminate the classic diffraction rings typically observed with hard-edged apertures.
