Large signal three-level superfluorescent fiber sources. |
摘要 |
<p>There is disclosed a new superfluorescent source comprising a long fiber doped with a lasing material presenting three-level transitions, such as Erbium. Due to the ground state signal absorption present in three-level systems, the source of the present invention can achieve backward signal quantum efficiencies well in excess of the limit of 0.5 exhibited by four-level systems. The source can be used in a Sagnac interferometer which may comprise an optical isolator because of possible high feedback. <IMAGE></p> |
