||Title Of Patent
||Large signal three-level superfluorescent fiber sources
||February 9, 1993|
|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 sig|
