Lasers
No great Pink Floyd show is complete
without lasers. For many people they can be the highlight of a
show, with many colors and patterns it becomes a brilliant
source of entertainment.How Lasers Work
"Laser" is an acronym for " light
amplification by stimulated emission of radiation". Lasers
are created when the electrons in a material are absorb
energy from an electrical current and become "excited".
These excited electrons move from a lower-energy orbit to a
higher-energy orbit around the atom's nucleus. Returning to
ground state causes the electrons to emit particles of
light.
