TLDR
In this paper, the ytterbium-doped, silica based, monomode fiber laser operating at discrete wavelengths in the range 1035nm to 1076nm is described.Abstract:
The last few years have seen intense interest and activity in the field of rare earth doped monomode fibre lasers and amplifiers [1,2],since these components could be used in fields as diverse as medicine and communications. Furthermore their small active volume offers a number of important advantages over conventional bulk glass lasers. We have chosen to investigate ytterbium doped fibre as it provides a very "clean" system (ie free from excite-q state absorption. Apart from the energy levels around 11,000cm there are no other levels until the ultra-violet). The ytterbium fibre laser should therefore offer a good system on which to test some of the basic physics of fibre lasers. In addition it offers 3-level, 4-level and quasi 3-level laser transitions. Published work on ytterbium doped glass lasers in bulk form has been sparse with the main publication being that of Snitzer [3]. In this paper we describe the characteristics of an ytterbium-doped, silica based, monomode fibre laser operating at discrete wavelengths in the range 1035nm to 1076nm.read more
