Free-electron laser irradiation can superheat tissue water, driving thermal vapor bubbles confined by tissue matrix and leading to mechanical tissue failure (ablation). Acoustic transients propagating from an ablation cavity were recorded with a polarization quadrature, interferometric vibrometer. For 3.0 μm infrared irradiation, the shocklike transients with peak pressures in the megapascal range indicate amplification due to bubble collapse. In contrast, for 6.45 μm irradiation, elastic transients with peak pressures in the 0.1 MPa range indicate tissue failure during bubble growth. © 2009 American Institute of Physics.
