| Research Abstract |
It is important for realizing the high-power fiber laser to clarify the origin of the laser damage which reduces the laser power. We investigated the correlation between the fiber glass structure and the laser induced defects, and searched the method suppressing the laser damage. We clarified the defects which reduces the laser power, and optimized concentrations of dopants in the fiber glass. We also found the glass treatment method to suppress the laser damage.
