A lab studying laser materials that open up new applications, and applications of semiconductor lasers.
AboutAbout the lab
Developing laser materials that open up new applications
The Composite Photonics Lab (Chikumoto Lab) is located at the Institute of Laser Engineering, Osaka University, and studies a broad range of topics, including the development of laser materials that open up new applications, system applications, and nanofabrication applications.
Lasers play a role in many fields of science, medicine, communications, and industry, such as high-precision optical instruments, optical communications, and laser processing.
In addition to laser technology, the lab works on superconducting materials in which electrons are in a coherent state, and on their application technologies.
Research is carried out in groups for materials and application technologies, semiconductor laser system engineering, and power laser photonics.
Key terms
- Coherent
- A state in which the phases of light or electron waves are aligned. Laser light has this property
- Magneto-optical imaging
- A method that uses the Faraday effect to observe the distribution of magnetic flux density as changes in light intensity
- LiDAR
- Technology that measures space in three dimensions with a laser. It is used to detect objects and people
