[Measurement of biological tissue destruction time after exposure to eximer XeCl laser]

Relationship between atherosclerotic patch destruction time under UV light from a XeCl laser and energy density of 1.3-4.7 J/cm2 has been studied experimentally. As energy density increased, the destruction time, estimated on the basis of exploring product release by continuous-wave He-Ne laser, decrease from 40 to 3.5 microseconds.
