Abstract
Potassium dihydrogen phosphate and its deuteride (KDP/DKDP) are the only tripled frequency crystals used for inertial confinement fusion. The photonic behavior of KDP under laser irradiation is unknown. In this study, the ultraviolet photon transport behavior of KDP with different growth environments has been simulated based on the Monte Carlo method. By comparison, it is shown that the linear absorption of filtered grown crystal is obviously weaker, and the relaxation time is much longer. Moreover, the concentration of defects inside KDP is the critical cause of linear absorption and relaxation time. Finally, the influence of multi-photon absorption on the damage of KDP is discussed.
期刊介绍：
The Optical Society (OSA) publishes high-quality, peer-reviewed articles in its portfolio of journals, which serve the full breadth of the optics and photonics community.
Optical Materials Express (OMEx), OSA''s open-access, rapid-review journal, primarily emphasizes advances in both conventional and novel optical materials, their properties, theory and modeling, synthesis and fabrication approaches for optics and photonics; how such materials contribute to novel optical behavior; and how they enable new or improved optical devices. The journal covers a full range of topics, including, but not limited to:
Artificially engineered optical structures
Biomaterials
Optical detector materials
Optical storage media
Materials for integrated optics
Nonlinear optical materials
Laser materials
Metamaterials
Nanomaterials
Organics and polymers
Soft materials
IR materials
Materials for fiber optics
Hybrid technologies
Materials for quantum photonics
Optical Materials Express considers original research articles, feature issue contributions, invited reviews, and comments on published articles. The Journal also publishes occasional short, timely opinion articles from experts and thought-leaders in the field on current or emerging topic areas that are generating significant interest.
