Comparative analysis of histological results of visible lesion thresholds for thermal and LIB induced skin damage at 1.3 μm and 1.5 μm

摘要

An assessment of skin damage caused by near-IR laser exposures is reported. The damage from two distinct laser-tissue temporal regimes is compared at two wavelengths (1.3 μm and 1.5 μm). Skin damage caused by thermal effects from single laser pulses is compared to damage caused by LIB (laser induced breakdown) using histological examinations. Modeling applications are explored to determine crossover points between thermal and photomechanical damage thresholds.
