Fatigue effect - decrease of Laser-Induced Damage Threshold (LIDT) of optical materials after extended exposure to laser pulses. While catastrophic damage is more prominent, the real threat comes from the subtle but destructive fatigue effect-induced color change mode of LIDT. This effect severely degrades any optical element, leading to a decrease in the overall performance of the laser system or even downtime. Unfortunately, this critical issue tends to be underestimated or even ignored.
