Abstract
Pulsed light is found to excite the intrinsic mechanical vibration modes of absorbing solid materials. The effect has been studied in seven piezoelectric solids using electrical detection of the vibrations. Arguments are given for a thermal mechanism, and transfer efficiencies of ∼10−9 are found for the conversion of visible energy into the mechanical energy of vibration. If the proposed mechanism is confirmed by further studies, the process should occur in all partially absorbing solid optical components.Keywords
