Web26. jun 2024. · Abstract. The laser-induced damage threshold (LIDT) of optical components is one of the major constraints in developing high-power ultrafast laser systems. Multi-layer dielectric (MLD) coatings ... The 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 and in applications where the laser induced modification or destruction of a material is the intended outcome.

WebThe LIDT measurement bases on the intentional damage of the samples surface. Therefore light is focused onto the sample to obtain a small spot diameter in the order of 50 µm to obtain high fluences. According to the expected damage threshold the laser pulse energy is varied in a range from no damage to total damage using constant spot size.
