Laser Damages (LIDT or LDT)
Laser Damage Threshold (LDT) or Laser Induced Damage Threshold (LIDT) is the limit at which an optic or material will be damaged by a laser given the fluence (energy per area), intensity (power per area), and wavelength. LDT values are relevant to both transmissive and reflective optical elements, coated and uncoated and in applications where the laser induced modification or destruction of a material is the intended outcome.
LDT (or LIDT) has two main issues:
a) Functionality of the optical system (optics elements - substrates and coatings) where failure of the durability of the element in LDT (or LIDT) will occur, and
b) Safety of the user.
