| Outline of Final Research Achievements |
This project was for establishing a new scheme of tunable fiber laser. I propose a very simple way to achieve a tunable laser skillfully using the chromatic aberration of a lens relay and a slit-like effect of the optical fiber core. The final results were not exactly the initial estimation of the project, but the tunable properties of fiber laser were partially achieved with installing a single-mode gain fiber and new optics and a new visible Q-switched fiber laser was developed with a saturable absorbed mirror in visible region in the same configuration of the tunable fiber laser. This means an emergency of new possibility of visible coherence light source.
