The paper aims to investigate the optical and spectroscopic properties of magnesium borax glasses doped with rare-earths. The optical absorption spectra were recorded at room temperature in the UV-Vis region. From the absorption edge studies, different radiative and optical properties have been evaluated to develop the fabrication processes for the implementation of integrated optical amplifiers and lasers to be used in optical communication systems as well as in medical systems and instrumentation.

Novel materials suitable for the development of new solid state, laser active media, as well as infrared to visible converters, continue to be of considerable scientific and technological interest. Photonic devices for high density optical storage and optoelectronics or medical diagnostics that exploit green light sources via frequency up-conversion are currently widely investigated (Brenier et al., 2005; Maciel et al., 2006; and Sun et al. , 2006). In general, application and utilities of glassy materials are enormous and are governed by factors like composition, refractive index and dopant present in the glasses (Jain et al., 2009). Samples with different rare-earth concentrations were synthesized, and their spectroscopic properties were discussed (Karapetyan et al., 2001; and Berneschi et al., 2006).
