概要
- 論文の詳細を見る
A pair of interfering near-IR femtosecond pulses from a mode-locked Ti:sapphire laser with a regenerative amplifier have been applied to wide-band-gap materials such a lithium fluoride (LiF) to create laser-active F2 and F3+ color centers and to encode nonerasable periodic gratings with fine fringe spacings of submicrometer size simultaneously. Using such a photon-written microstructure, a distributed-feedback LiF laser oscillation based on F2 color centers has been realized at room temperature. A lasing output performance with a linewidth of less than 1 nm, slope efficiency of ${\sim}10$%, and beam divergence of ${\sim}20$ mrad was obtained at 710 nm.
