We have assembled a single-transverse-mode, single-longitudinal-mode ruby laser with a pulse length of ∼6–12 ns (intensity half-height full width). Pulsed holograms have been made by use of this laser. The laser carrier-frequency shift (or chirp) has been measured and is found to be the limiting factor on the depth of field of the hologram. In order to demonstrate this, we present a quantitative measurement of hologram quality.
