We have developed high damage threshold filters to modify the spatial profile of a high energy laser beam. The filters are formed by laser ablation of a transmissive window. The ablation sites constitute scattering centers which can be filtered in a subsequent spatial filter. By creating the filters in dielectric materials, we see an increased laser-induced damage threshold from previous filters created using ‘metal on glass’ lithography.

简介：
根据给定的信息，我们可以从《赵丽词汇5500讲义精校版》中提炼出以下相关的知识点： ### 1. 单词理解和运用 #### 1.1 bleak（荒凉的、萧条的） - **含义**：形容一个地方缺乏生机、显得荒凉或者萧条。
- **例句**：The living conditions in the village were bleak due to the harsh winter. #### 1.2 haunted（闹鬼的、萦绕心头的） - **含义**：指某个地方被认为有鬼魂出没或某事长期困扰人心。
- **例句**：The old mansion is said to be haunted by the ghost of its former owner. #### 1.3 gaunt（憔悴的、瘦削的） - **含义**：形容人因病痛或饥饿而显得憔悴、瘦削的样子。
- **例句**：After the long illness, his face had become gaunt and his eyes sunken. #### 1.4 acumen（敏锐、机智） - **含义**：指个人在处理问题时展现出的敏锐洞察力和智慧。
- **例句**：Her business acumen was evident in her quick decision-making abilities. #### 1.5 abnormal（不正常的、异常的） - **含义**：指与正常情况不符的状态或行为。
- **例句**：The patients body temperature remained abnormally high for several days, reaching up to 40.5 degrees Celsius. #### 1.6 abundant（丰富的、充裕的） - **含义**：指某种资源或条件极其丰富、充裕。
- **例句**：Texas is abundant in natural resources such as oil and gas. #### 1.7 access（进入、获取） - **含义**：指能够到达某个地点或获得某种资源的能力。
- **例句**：Access to some parts of South America is still difficult due to dense forests covering large areas. #### 1.8 account（考虑、账户） - **含义**：指在做出决定前考虑某个因素，或指银行账户等。
- **例句**：I hope my teacher will take my recent illness into account when judging my examination performance. #### 1.9 adjust（调整、调节） - **含义**：指根据特定环境或需求改变某些设置或状态。

在日常工作中，钉钉打卡成了我生活中不可或缺的一部分。然而，有时候这个看似简单的任务却给我带来了不少烦恼。
每天早晚，我总是得牢记打开钉钉应用，点击"工作台"，再找到"考勤打卡"进行签到。有时候因为工作忙碌，会忘记打卡，导致考勤异常，影响当月的工作评价。而且，由于我使用的是苹果手机，有时候系统更新后，钉钉的某些功能会出现异常，使得打卡变得更加麻烦。
另外，我的家人使用的是安卓手机，他们也经常抱怨钉钉打卡的繁琐。尤其是对于那些不太熟悉手机操作的长辈来说，每次打卡都是一次挑战。他们总是担心自己会操作失误，导致打卡失败。
为了解决这些烦恼，我开始思考是否可以通过编写一个全自动化脚本来实现钉钉打卡。经过一段时间的摸索和学习，我终于成功编写出了一个适用于苹果和安卓系统的钉钉打卡脚本。
