Abstract
Simultaneous measurements of laser excited ultrasonic waves in a solid sample and in the surrounding air are used for characterizing plasma absorption and the plasma shielding effect. Typical modifications of u ltrasonic waves are discussed and the acoustic energy distribution bet ween the solid and the atmosphere is assessed by a comparative analysi s of optoacoustic responses received from both probes.
