| Outline of Final Research Achievements |
Recently, performance of free-electron-lasers are greatly improved by combining a laser system to introduce a modulation in an electron beam, called seeding. In order to upgrade the system to a high averaged power system operating in a high repetition rate CW mode, development of the laser system to be usable in such a time structure also. An optical cavity system is a candidate. To realize a high enhancement gain and a short pulse duration, some special techniques are necessary. We developed a fiber mode-locked laser with a fast controllable system using an EOM, and a CEP tuning system using an AOM for the purpose. We have demonstrated to control resonance of a build-up cavity with the laser oscillator.
