In the first part of our webinar miniseries on high precision metrology we give a brief introduction to the language of frequency metrology:
- Reviewing time and frequency domain quantities such as Allan deviation, phase noise and timing jitter
- Explaining the need for stable oscillators and the levels of performance for different applications
- Presenting the concept of the laser linewidth and the Pound-Drever-Hall laser stabilization
- Comparing the performance of high-end quartz, microwave, and optical oscillators, and reviewing the rules of their fair comparison
Menlo Systems 超稳激光网络研讨会第一期简单介绍时间频率计量领域所用的语言，主要包括：
首先介绍阿伦方差、相位噪声、时间抖动等时频计量所用的概念；
接下来解释超稳振荡器的用途以及它们可以达到的性能；
最后用时频相关的概念统一地比较高稳晶振、微波振荡器以及光学振荡器的性能。
Menlo诚挚地邀请相关领域的研究人员、学生、实验员以及所有对超稳激光器以及时间频率计量技术感兴趣的观众和朋友参加此次网络研讨会。
