Laser-induced Dynamic Gratings Instant

: Two laser beams intersect in a photosensitive medium (solid, liquid, or gas).

: Ionization in gases or solids to create high-density electron patterns. Laser-Induced Dynamic Gratings

(LIDGs) are temporary optical structures created when two or more coherent laser beams interfere within a material. Unlike permanent gratings etched into glass, these "transient" patterns exist only while the light is present, making them vital for real-time optical processing. How They Work : Two laser beams intersect in a photosensitive
