Laser damage thresholds depend on the amount of energy absorbed, and in this specific case, energy absorbed by the retina. The goal of our research is to simulate a supercontinuum laser source and compare the resulting damage to that of the current ANSI approach. To calculate retinal damage we utilize the Arrhenius integral, which returns numerical values for laser-induced damage with values ranging from zero to one depending on the severity. Our simulations use numerical analysis to iterate through different coordinates in space and time to return data representative of the physical situation after we expose the eye to a gaussian laser beam. We have performed simulations ranging from a singular laser source up to a three-laser source and are currently working towards an automated method of generating these complex configurations in the hopes of more efficiently replicating the damage properties of a specific laser product and comparing it to the existing ANSI approach.
