Abstract
Spectral programming of stimulated photon echoes is presented. The preparation pulses — pulse #1 and #2 of the three pulses of the echo sequence—are substituted by writing a frequency dependent modulation into the inhomogenously broadened absorption line of a persistent spectral holeburning material. A holographic setup is used, and arbitrarily predefined echo signals can be generated. Linear response theory is applied to calculate the required modulation of both the intensity of the write beam and the holographic spatial phase as a function of optical frequency. Experimental results are shown using a Pr 3+:Y 2SiO 5 crystal at cryogenic temperatures.
