Research Summary

Shinichi_Imai(Ph.D.) Masaki Yumoto

The mid-infrared region holds many molecular fingerprint signatures important in various sensing applications. We are going to realize mid-infrared laser light source which can be equipped with in the vehicles, drones and instrumentations for these purposes. The light source consists of fundamental laser light and optical-nonlinear devices. We would like to make their size much more compact with advanced concepts of laser configurations.
