Saturable absorber

Explanation of the basic principles and applications of "saturable absorption materials" and "saturable absorption mechanisms."

"Saturable absorption" refers to the phenomenon where a material absorbs light when the intensity of the incident light is low, but allows light to pass through when the intensity is high. Objects with such properties are called "saturable absorbers (SA)," but in practice, there are "saturable absorption materials" that achieve saturable absorption through the characteristics of the material, as well as "saturable absorption mechanisms" that realize similar functions through mechanical operation or optical systems. In this article, we will collectively refer to these as "saturable absorbers" and provide detailed explanations for each.
