Some experiments performed with a reflected-light pulsed-laser holography system

A short-exposure, high-energy holography system has been constructed which yields high quality holograms of scenes several cubic meters in volume. The system is constructed around a single mode Q-switched ruby oscillator and a 20-dB gain single-pass ruby amplifier. The output is fully coherent at peak output of 10 J. Front lit holograms of transient events and of live subjects have been made with this system.
