Multiple-cavity lasers for holography
Abstract
The use of multiple-cavity lasers in holography and photography is described. By splitting up a ruby laser cavity and using part of the crystal for different cavities, a number of interesting possibilities result. Eight basically different configurations are discussed to show how the normally oversized crystal in commercially available lasers can be used to advantage. These result in lasers that become ideal sources for some applications, such as ultrahigh repetition rate, stereo holography, multiple reference wave, simultaneous front and back lighting, multiple framing, and other techniques.
