Abstract
The invention relates to a Nd-doped, aluminate-based or silicate-based, laser glass having a peak emission wavelength that is longer than 1059.7 nm, an emission cross section (σem) of ≧1.5×10−20 cm2, and/or an emission bandwidth (Δλeff) of ≧28 nm, while maintaining properties that render the glass suitable for commercial use, such as low glass transition temperature Tg and low nonlinear index, n2.
