摘要：

The optical attenuation coefficient for human aorta has been measured in the 440-500 nm spectral region using the transient photoacoustic (thermoelastic) response produced by an excimer-laser-pumped dye laser. It is confirmed that diseased tissue has a significantly higher attenuation than normal samples in this spectral region. The maximum difference occurs at ∼480 nm and there is a lowering of the ablation threshold fluence for diseased tissue by a factor of ∼1.5 for dye laser ablation at this wavelength. © 1990 Springer-Verlag.
