An Improved Method of Fabricating Rare Earth Doped Optical Fiber

Tunable Rare-Earth Doped Fiber Laser

Radiation Effects Expected for Fiber Laser/Amplifier Rare Earth Doped Optical Fiber

1.0 Introduction Fiber lasers are still considered an emerging technology because at the system level there exists no harsh environmental qualification data that is available to the public. Some vendors such as IPG claim to have thermal and vibration data on their units but NASA still needs to conduct validation analysis and testing to insure the technology will function as expected under harsh...

Coupled solitons in rare-earth doped two-mode fiber.

We present first ever analytical solutions for shape-preserving pulses in a Kerr nonlinear two-mode fiber doped with 3-level ? atoms. The two modes are near-resonant with the two transitions of the atomic system. We show the existence of quasi-stable coupled bright-dark pairs if the group velocity dispersion has opposite signs at the two mode frequencies. We demonstrate the remarkable possibili...
