AI Overview
Eye-safe laser crystals, such as Er:Glass (1535 nm/1540 nm) and Cr,Tm,Ho:YAG (2080 nm), are gain media that produce light in the >1.4
m range, ensuring light is absorbed by the eye's cornea/lens rather than the retina, minimizing risk of permanent damage. These materials are ideal for LIDAR, remote sensing, and military rangefinders.
