【Abstract】 New progresses of KDP crystals in the study of laser damage threshold in recent ten years are reviewed in this paper.The effects of metal ions and two photon absorption on the laser damage threshold of KDP crystals is also described.When damage occurs,it is certainly associated with a localized heating of the crystal which results from metal ions and two photon absorption.The mechanism of the laser damage threshold of KDP crystals is discussed,and the new ideas are brought out about the future developing direction.更多还原
