Damage Integral and Other Predictive Formulas for Non-isothermal Heating During Laser Exposure

Abstract

Physics-based models supply simulated temperature rises to photothermal damage rate models, and provide comprehensive riskassessments for laser-induced damage. As the physics-based models continue to be refined, the damage rate models have not advanced. This peculiar lack of improvement is counterintuitive considering the damage integral (O), originally derived for isothermal heating events, fails to accurately represent the non-isothermal heating from laser exposures.
