A self-pumped phase conjugating mirror in conjunction with a traveling-wave acousto-optic modulator can be used to derive a spatially undisplaced frequency translatable optical beam. One can also obtain a beam consisting of multiple optical frequencies spaced by twice the modulator drive frequency. We find that the appropriate measure of the phase conjugating mirror's ability to retroreflect a moving optical beam can be its response (writing) time, its memory time, or the ratio of the two, depending on how the beam is moving.

    We demonstrate photoacoustic thermal imaging of the voids occurring at the interface of directly bonded silicon wafers. The wafers are not touched by probes, minimizing wafer contamination, and the technique does not require the outer surfaces of the bonded wafers to be polished. The method is...
