The WP interferometry (WPI) is the most fundamental method in the WP manipulation. However, WPI with 100% contrast has never been measured so far on atoms and molecules. Our WPI technique lays its heart in controlling quantum phases of WPs with attoseconds accuracy. We have recently achieved almost 100% contrast in nuclear WPI by means of the double-pulse pump/control method. The interpulse-delay is tuned with accuracy better than 5 attoseconds. Model calculations have been made also to study the interaction of two nuclear WPs aiming at searching coherent control methods of encoding and decoding specific information on a molecule. |
