Influence of radiation wavelength on elastic pulse shape during laser excitation
Abstract
The influence of radiation wavelength on the shape of laser excited elastic pulses is investigated to explain the mechanism underlying the optical generation of sound. The experimental setup is described, and the calculated values are shown to agree well with the experimental findings. The wavelength of the laser radiation is found to have a strong influence on the shape of the electric pulses, which must be taken into account in investigations of the optical generation of plastic waves.
