| 英文摘要 | Laser-induced bulk damage in potassium dihydrogen phosphate (KDP) and its deuterated analog (DKDP) crystals for nanosecond pulses is caused by light-absorbing precursor defects, which are formed during crystal growth. However, current chemical analysis and spectroscopy techniques fail to identify the nature of the responsible precursor defects because of their "invisible" concentration and/or size. In this study, the aim was to explore a novel method for understanding laser matter interactions with regard to physical parameters, such as size and concentration, affecting the ability of damage precursors to initiate damage. Laser-induced damage performance at 1064 nm of KDP crystals grown using filters of different pore sizes was investigated. By reducing the pore size of filters in continuous filtration growth, laser damage resistance was improved. Furthermore, a model based on a Gaussian distribution of precursor thresholds and heat transfer was developed to obtain a concentration and/or size distribution of the precursor defects. The results revealed that smaller size and/or lower concentration of precursor defects could lead to better damage resistance. |
