: A third "probe" beam hits this temporary structure and is diffracted, allowing researchers to measure the material's internal dynamics in real-time. Key Applications Laser-Induced Dynamic Gratings | Springer Nature Link

: Localized heating that changes the medium's refractive index. 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.
