RIKEN Baton Zone Program Mid-Infrared Laser Source Laboratory
Team Leader: Shinichi Imai(Ph.D.)
Deputy Team Leader: Masaki Yumoto (Ph.D.)
Research Summary


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.
