Laser damage threshold

                              The laser damage threshold (LDT) or laser induced damage threshold (LIDT) is the limit at which an optic or material will be harmed by a laser given the fluence, intensity (power per area), and wavelength. LDT values are pertinent to both transmissive and intelligent optical components and in applications where the laser prompted alteration or demolition of a material is the expected result. Optical frameworks can relieve the impacts of laser harm both by expanding the LDT of the optics utilized and by changing the laser shaft qualities. The utilization of high reflectivity (HR) dielectric mirrors rather than metal mirrors is a common strategy.
