Key Takeaways: Laser-Induced Damage Threshold (LIDT) defines the laser energy or power at which materials sustain permanent damage. It varies with laser type—pulsed or continuous—and is influenced by factors like pulse duration, wavelength, material defects, and thermal properties. Pulsed lasers often cause non-thermal damage via ionization, while CW lasers primarily induce thermal effects. Testing methods […]
