Abstract
Laser induced, breakdown-generated sound pulses in air were studied in the zero to 200 kHz frequency range. Theoretical predictions, based o n a theory originally developed for macroscopic blast waves, were used to predict peak sound pressure, power spectra and pulse peak-to-peak time. The predictions were found to agree with the measured data withi n the accuracy of the measured and predicted parameters for laser puls e energy in the 100 mJ range.
