| Outline of Final Research Achievements |
Mid-infrared region with a wavelength of 2 to 10 micrometer is important wavelength band in both science and engineering, such as the presence of many molecular absorption lines and transmission to important materials in the semiconductor field such as silicon and germanium. However, at present, lasers in this region are very limited at present. In this study, we developed basic technology to develop a mid-infrared laser. Q-switched mid-infrared laser generation by ring laser development has been achieved.

| Academic Significance and Societal Importance of the Research Achievements |
本研究で開発した中赤外線レーザーシステムは例えば環境センシング（分子の種類や濃度を観測する）や可視光では観測できない金属材料や粗表面の計測に用いることができる．また開発したパルスレーザーは連続波レーザーに比べて高強度であるため，樹脂やガラス，金属，半導体に対して切断等の加工に用いることもできると考えられる．また，本研究をさらに発展させて，この領域での光周波数コム開発も可能である．
