ABSTRACT: Fluorophosphate glasses represent a

favorable compromise between the requirements of

low non-linear refractive index (fluoride glass) and

high cross section (phosphate glasses) for

laser materials application. In this work, we introduce

a new series of glass materials for broadband

and eye-safe laser source applications: (Mg,

Ba)F2-based fluoride glasses incorporated

with metaphosphate compounds. Since this new

series of glass can be doped by Yb 3+ ions with

a relatively high dopant concentration, they are

expected to be a good candidate for compact fiber and

waveguide laser applications. In this regard, various

optical and spectroscopic characterizations have

been performed.
