In this paper we investigate photodarkening and photobleaching impact in 1030 nm ytterbium doped fiber lasers and we compare results with previous experiments made with 1070 nm fiber lasers built from the same kind of alumino-silicate fiber. The possibility of using a common model with no free parameters may suggest that lower photodarkening experienced in 1030 nm fiber lasers is simply due to lower inversion required, with no influence due to the wavelength of laser photons.

Abstract
In this paper we investigate photodarkening and photobleaching impact in 1030 nm ytterbium doped fiber lasers and we compare results with previous experiments made with 1070 nm fiber lasers built from the same kind of alumino-silicate fiber. The possibility of using a common model with no free parameters may suggest that lower photodarkening experienced in 1030 nm fiber lasers is simply due to lower inversion required, with no influence due to the wavelength of laser photons.File in questo prodotto:
