The beam of light emitted by a conven-tional pulse laser is a summation of a number of transverse and axial resonance frequency modes. This type of laser is not suitable for making holograms except with a very specific arrangement of the laser light, object, and photographic plate (Ref. 1-3). In this arrangement, the object is illuminated from behind. Thus, an observer looking through the hologram plate at the reconstructed image sees only the outline or shadow of the object. Obviously, this technique is inadequate when the observer desires to discern surface detail on the holographed object.
