The general public is becoming increasingly aware of the many applications of lasers: in scientific research, medicine, engineering, communications, manufacturing, holography, and certainly entertainment and the arts. These sophisticated sources of infrared, visible, and ultraviolet light energy have even become a part of science–fiction folklore; no respectable futuristic film of the “Star Wars” variety would be without an arsenal of laser–inspired weaponry and visual effects. While more earthbound, our concerns in this article relate to the technology, much of it based in audio–frequency electronic devices, which permit the control of laser beams for applications in the performing arts.
