Simulated Supercontinuum Generation in the Human Eye from 1200 nm to 1400 nm

Abstract

To understand the possible eye safety implications of supercontinuum generation in the human eye, a one-dimensional simulation was created by extending a femtosecond wave propagator previously used by the Air Force Research Lab to incorporate phase-modulation and self-focusing effects. Simulation of femtosecond MPE limit pulses propagating in the human eye demonstrate multiple hazards not anticipated from longer pulse duration studies including: a hazard from the broad pulse bandwidth required to form femtosecond pulses, self-phase modulation generating shorter frequency light, and self-focusing generating plasma near the retina. These results provide guidance for future experimental studies of retinal exposure to femtosecond pulses and lay the foundation for future two-dimensional modeling of nonlinear effects in the human eye.
