Characterization of improved laser phosphate glasses

Improved laser phosphate glasses were obtained varying the glass formula with Ba
²⁺
and Sr
²⁺
. The absorptive nonlinear optical (NLO) response at two regimes was used for monitoring the figure of merit of glass media. The NLO response efficiency is affected by Sr
²⁺
addition. The equimolar ratio of Ba
²⁺
to Sr
²⁺
in the host glass matrix gives improved composition with the lowest value of Im(x
⁽¹³⁾
) and highest matrix rigidity. UV-Vis analysis confirms the observations obtained from an analysis of optical scattering. The mixed Sr/Ba laser glasses supposed to have a high potential in the field of laser optics.
