| 摘 要： | 在确定光学薄膜激光损伤阈值的实验数据处理过程中，发现一些样品的数据点分布偏离直线型式。对此，用国际标准规定的零几率来确定损伤阈值的同时，对测试数据点采用了不同的非直线拟合，也得到一个零几率损伤阈值。比较两者差异，并与实验测试结果对照，发现这些样品采用非直线拟合得出的零几率损伤阈值与实际情况更接近一些。

| Abstract: | In process of the arranging experiment data for determining the damage threshold, it is found in some samples that the distribution of the data points of the experiment results deviates obviously from the linear distribution. Under this situation, as the damage threshold is determined from the linear extrapolation of the measured energy density dependent damage probability based on the ISO11254, another damage threshold of zero probability is obtained by the different non linear fit of the experiment data. After making a comparison between these two values and contrasting them with the experiment results, it is obtained from some samples that the damage threshold of zero probability extrapolated by the non linear fit is more close to the “real” damage threshold. |
