摘要

We report what is to our knowledge the first experimental observation of two- and three-pulse echoes in Er3+:YAG at 1.527 mu m. The experiment was performed on the transition from the I-4(15/2) ground state to the lowest Stark level of the I-4(13/2) excited state. The corresponding homogeneous dephasing time was measured to be approximately 50 ns at 1 and 7 K. In addition, three-pulse echo decay indicated a lifetime of the spectral grating of similar to 30 mu s. Implications of these results for optical data storage and optical signal processing are discussed. (C) 1997 Optical Society of America.
