Optics

  • Nonlinear optics laboratory: We study the nonlinear optical characteristics of diverse materials such as semiconductor, molecules, and organics molecular thin films using various lasers. In particular, we are focusing on developing the coherent light source which can cover wide wavelength ranges using optical parametric resonances.

  • Quantum chaos and application laboratory: Our main focus is on the 2-dim laser and ultra small random laser as applications of quantum chaos. These lasers are being developed with a view to the application of optoelectronics source, optical communication source, chemical/biological sensor. It can also be a very useful tool in investigating the mesoscopic systems.
