Title:
共鳴ファブリ-ペロ半導体可飽和吸収体と2光子吸収パワー制限器
Document Type and Number:
Japanese Patent JP4559562
Kind Code:
B2
Abstract:
An intracavity resonant Fabry-Perot saturable absorber (R-FPSA) induces modelocking in a laser such as a fiber laser. An optical limiter such as a two photon absorber (TPA) can be used in conjunction with the R-FPSA, so that Q-switching is inhibited, resulting in laser output that is cw modelocked. By using both an R-FPSA and a TPA, the Q-switched modelocked behavior of a fiber laser is observed to evolve into cw modelocking.
