Recently developed optical methods of holographically generating                coherent ultrasonics will be employed to produce coherent sound waves           with extremely high frequencies that are continuously tunable.  These           features, coupled with the ability to optically inject acoustic probes          without mechanical contact, makes the proposed technique well suited            for the non-destructive evaluation of materials.
