| The main focus of our research is the development of the
measurement techniques that are capable of detecting quite small but
important effects for further understanding of nature. One of the
most important examples of such effects is the gravitational wave; this is the wave propagation of gravitation interaction, predicted by
Einstein's general theory of relativity.|
Its effects are too small to be detected so far, even though efforts for over 40 years have been made in order to realize direct
detection on the Earth. However, the development of precision laser
interferometry could make it now possible; huge laser
interferometers have been constructed recently all over the world
in pursuit of this goal. Our group is taking part in the Japanese research group and is engaged in developing optical systems for
gravitational wave detectors. The research projects that we are
currently working on are as follows:
1. High-power and stable lasers for gravitational wave detectors
2. Development of control and stabilization techniques for laser frequency and intensity
3. Evaluation of high quality optical elements
4. Novel interferometry techniques for extremely small vibration measurement
5. Characterization of fundamental noise phenomena (thermal noise, quantum noise) and related physics
6. Characterization of high performance damping metal for the elimination of vibrational

|Messages to Students|
All schools should have rigid beliefs, which should not be changed easily, even in the face of potential social opposition.|
Young students should acquire the necessary basic knowledge and experience in school; they are necessary for understanding facts and to create
new. I strongly recommend you to study a wide range of basic
science as well as fashionable subjects.
