A new source of coherent light energy is proposed for pulsed holographic applications. The proposed new source is the dye laser, whose active medium is a solution of one of several possible organic dyes. The most interesting properties of the dye laser pertinent to pulsed halography include high power capability with high efficiency, tunability across the visible spectrum, high reliability, and low cost of materials. Dyes can be selected and tuned to match the optimum transmissivity of the working medium. Because dye lasers can operate at two or more tunable frequencies, they are of potential importance in halographic contouring, which is a method for obtaining three-dimensional holographic images with range contours superimposed on the complex three-dimensional objects. The selective interaction of dye laser light with living organisms may permit minute dimensional changes to be observed. Modified author abstract
