Laser-induced damage threshold

The Laser-Induced Damage Threshold (LIDT) is the maximum laser energy or intensity that a material, like an optical component, can handle without suffering damage such as cracks, pits, or clouding. It defines the safe operational limit to prevent degradation or failure when the material is exposed to laser light. LIDT depends on factors like laser wavelength, pulse duration, and material properties. Knowing this threshold helps engineers design laser systems that operate effectively without damaging the components, ensuring longevity, safety, and optimal performance.
