Paper Abstract

Comparison of the eye tissue transmission for two (1.08 μm and 1.34 μm) Nd:YAP laser wavelengths was done. The lasers were working in pulsed free-running regime. The interaction energy of ~100 mJ and spot diameter of 5 mm was used for both wavelengths yielding in the radiation fluence ~0.51 J/cm2 (8500 W/cm2). From the step by step transmission measurement of the human eye globe layers (in vitro) was recognized that the value of the absorbed energy in particular segments was different for monitoring wavelengths yielding in the two orders fluence difference on the retina. From the results follows that the 1.34 μm radiation is absorbed mainly by the first segments of the eye in contrast to 1.08 μm for which the main part of the radiation going through all eye layers.
