| Abstract: | An effective continuous filtration crystallizer was developed to grow KDP crystal by temperature reduction method.Ultra-microscopy,X-ray photography and laser damage threshold were adopted in characterizing the quality of crystal.The results show that under the condition of continuous filtration,the formation of inclusions and dislocations in crystal is significantly reduced,and the laser damage threshold of crystal under radiation at wavelength 355 nm is improved by about 30%. |
| Keywords: | KDP crystal continuous filtration inclusions dislocations laser damage threshold |
