Syllabus
Course overview and goals
The light has several properties such as frequency, polarization, and phase, and so on. The light measurement using these properties is used for a lot of fields. In the lecture, several methods of spectroscopy are treated theoretically through the interaction between an atom and light. Moreover, the principle of the Michelson interference and cavity of light for detecting gravitational waves is explained including the constitution of gravitational-wave detectors.
Course description and aims
The aim is to explain various kinds of measurement methods using laser light in your own word as well as to understanding the outline of the methods. Especially, it is significant to calculate the various parameters of the interaction between atoms and light and gravitational-wave detection techniques concretely.

Course schedule/Objectives
| Course schedule | Objectives | |
|---|---|---|
| Class 1 | Basic property of lasers | The light property and several kinds of lasers are introduced. |
| Class 2 | Laser measurement | A variety of measurement methods using lasers are explained. |
| Class 3 | Semiclassical theory of atom-light interaction | The absorption and dispersion of light caused by an interaction between light and an atom are explained. The phenomenon of Electromagnetically induced transparency is introduced. The theory is treated as semiclassical. |
| Class 4 | Coherent and squeezed states of the light | The squeezed state that appears when the electromagnetic field is treated in quantum theory is explained. Moreover, the generation method of the squeezed state is also introduced. |
| Class 5 | Detection method of the gravitational wave | The property of the gravitational wave and the detection method using the Michelson interferometer are explained. |
| Class 6 | Present status of the gravitational wave detectors (1) | The present status of the gravitational-wave detectors is introduced. |
| Class 7 | Present status of the gravitational wave detectors (2) | The status of the next-generation gravitational-wave detectors is introduced. |
Study advice (preparation and review)
To enhance effective learning, students are encouraged to spend approximately 100 minutes preparing for class and another 100 minutes reviewing class content afterwards (including assignments) for each class.
They should do so by referring to textbooks and other course material.
