1.  Dr. Tadataka Edamura, Hamamatsu Photonics KK, JAPAN
Invited Talk: Recent progress on Quantum Cascade Lasers development and Mid-IR applications
Speaker Biography: Tadataka Edamura received B.S., M.S. ansd Doctor degrees, all in applied physics, from Keio University, Yokohama, Japan, in 1990, 1992 and 1995 respectively. In 1995, he joined the Central Research Labs, HAMAMATSU PHOTONICS. Since 2010, he has been the Senior Researcher of the Material Research Group.

Summary: During the last decade, the development of Mid-IR (4-11 μm) Quantum Cascade Lasers (QCLs) has shown a substantial progress leading to the commercial availability of such devices. In developing newly high performance QCLs, we have focused high output power QCL for laser surgery. Recently, the selective caries removal treatment technique without serious thermal damage for a normal dentin has been required. The potential application of selective caries removal by high output power QCL emitting at 6μm wavelength range is investigated. This wavelength range is expected to be absorbed to organic matter (for example, Amide I -band). We will present the latest status of the Mid-IR QCLs together with the some results of demonstrations for medical applications; selective caries removal treatment.
