Abstract

Volume holographic recording and storage in Fe‐doped LiNbO₃ using single 30–75‐nsec duration optical pulses at 694.3 and 531 nm from Q‐switched ruby and frequency‐doubled Nd:glass lasers, respectively, is reported. The recording sensitivity for a pulsed writing source is found to be better than that estimated for a cw source. A sensitivity of 2 mJ/cm² at 476 nm and 2.5 mJ/cm² at 488 nm to record a hologram of 1% diffraction efficiency is the best sensitivity figure yet reported. The orders of magnitude of improvement in sensitivity is attributed to higher fractional concentration of Fe²⁺.
