| Outline of Final Research Achievements |
With the progress of solid-state laser technology, compact, highly efficient, highly reliable, and high-power laser light sources have been put to practical use in industrial, medical, scientific and other fields. Demands for laser light sources are becoming sophisticated and diversified, so various researches aiming such as high power, short pulse, high efficiency, new wavelength band. In this research, focusing on the development of a new wavelength band in the mid-infrared region which is one of the challenging issue, we developed a highly efficient 2.8-micrometer-band solid-state laser source using Er-doped materials.
