Paper Abstract

Although most laser injuries involve a beam which is tightly focused on the retina, some laser or laser-derived sources are inherently non-focusable and produce a large image. These sources include nonlinear optical limiters, which might be used to protect the eye against injury. Nonlinear refraction, scattering, and other processes in these devices degrade the focusability of the beam. The resultant retinal image is complex in shape, contain both focusable and non- focusable components. This paper will review the influence of these processes in different types of limiter and will examine the issues which affect retinal damage threshold for these and other large-image sources. Recent experimental data will be discussed in the light of physical models.
