| 摘 要： | 利用HJ - 4型连续CO2 激光对金刚石膜进行了激光损伤阈值的研究,损伤后的金刚石膜用SEM和Raman进行了表征。研究结果表明,高质量CVD自支撑金刚石膜具有较高的
激光损伤阈值,金刚石膜抗连续激光损伤阈值的范围是在1. 15 ×106 ～2. 26 ×106W / cm2。金刚石膜激光损伤主要是由于热震损伤,其机制属于热- 力耦合机制。

| Abstract: | Laser damage threshold value of high-quality CVD freestanding diamond films is investigated by CO2 CW2 laser. The damaged diamond films are characterized by SEM and Raman spectra. The results show that high-quality
CVD freestanding diamond films have higher laser damage threshold value, its value changed from 1. 15 ×106 to 2. 26×106 W / cm2. The laser damage of diamond film is because of thermal shock damage, itsmechanism is thermo-force coup ling |
