Which of the following co-dopant is not employed by neodymium and erbium doped silica fiber lasers?

Question

Quizplus · Accepted Answer

Nitrogen is not typically used as a co-dopant in neodymium and erbium doped silica fiber lasers. The common co-dopants are phosphorus pentoxide, germania, and alumina, which help in modifying the core refractive index, improving the solubility of the rare-earth ions, and altering the laser properties. Nitrogen doping is less common and not standard for these types of fiber lasers.
