Catastrophic Optical Damage (COD)

Catastrophic Optical Damage (COD) refers to the sudden failure of optical components, such as lenses or mirrors, when they are exposed to intense laser light. This excessive energy can cause physical changes, like melting or cracking, leading to permanent damage. COD typically occurs when the material's energy threshold is exceeded, resulting in a rapid breakdown. It's a critical concern in fields involving high-power lasers, as it can compromise equipment and safety. Understanding COD helps engineers design better optical systems that can withstand high levels of light without failing.
