Laser art uses material that originates in different branches of physics and engineering. Only an exceptional person is familiar with all concepts and relations that are bound to playa role in the discussion of the various phases of this art. Therefore, it is probably worthwhile to present in summary form the ideas and results needed from physics and other disciplines. Most of this material is discussed in undergraduate courses in optics, modern physics, and atomic theory; therefore the summary… CONTINUE READING
