Z-Scan Measurement of Water in the Near-Infrared Regime

Abstract

Current ocular laser safety standards are based on experimental studies of CW exposures of multiple seconds to pulses as short as 100 fs. A previous study raised concerns that nonlinear processes such as supercontinuum generation may pose retinal hazards not anticipated under current eye safety standards. The nonlinear optical properties of distilled water in the near-IR region were studied using the Z-scan technique for wavelengths between 1150 nm and 1400 nm.
