Abstract
A self-pumped atomic sodium phase-conjugate mirror was modified to include an amplitude modulator, which thus formed a device capable of encoding temporal information onto the phase-conjugate return beam. Modulation rates of as much as 4 MHz with modulation depths in the range of 70–90% (both limited by the electronics and the modulator) have been obtained by using an intracavity acousto-optic modulator.
