To realize the seeding for an FEL, we are developing a mid-infrared light source based on a difference frequency generation between the light pulse of the fiber laser and its wavelength shifting. We report the overview of the CEP stabilized mid-infrared light source for seeding an FEL oscillator, and the present situation of the fiber laser development.}, pages = {780--782}, title = {キャリアエンベロープ位相安定中赤外光源の検討}, year = {2019} }
