| 摘 要： | 采用输出特性不同的几种激光器测量了多种介质光学薄膜的破坏阈值，并对典型的破坏过程进行显微分析。研究了激光输出特性的不同对薄膜损伤效果的影响:在相同能量输出的条件下，脉冲激光比连续激光更容易形成有效的破坏；连续激光则能通过能量积累而更容易对作用目标造成烧蚀破坏。

| Abstract: | Laser induced damage thresholds (LIDT) of several kinds of optical dielectric coatings were measured using some lasers with different output characteristics. Typical damage process was discovered through microcosmic analysis of coatings. In particular, the influences of laser output characteristics on laser induced damage statuses in coatings were investigated. It's given that a pulsed laser is easier to damage an objective than a continuous wave laser in condition of the same laser energy. However, CW laser can easily cause ablation damage in objectives by accumulation of energy． |
