Store and retrieval process with tunable storage time. a Storing process: the optical data pulse is depleted by the counter-propagating write pulse, transferring the carried information to the acoustic phonon. The curves show the transmitted data pulse for different write pulse powers: black: original data, red: 1.1 W, blue 2.0 W, purple: 3.0 W, green: 4.7 W. Depletion of more than 90% can be achieved. b Retrieved data pulses after different storage times. The inset shows a zoomed-in version of the retrieved data pulses. c Original data pulse (red) super-imposed with the retrieved data pulses after 3.5 ns (black) and 5.5 ns (blue) respectively; the details of the original shape can be distinguished in the retrieved data pulses
