Evaluation of laser level populations of erbium-doped glasses

Optical absorption and structural studies of bismuth borate glasses containing Er3+ ions

“…These glasses are better competitors for optical transmission studies due to their long infrared (IR) cut-off [1,2]. On the other hand, the heavy metal oxide glasses such as; the bismuthate glasses have attracted an important interest for optoelectronic and photonic applications because of their important properties such as higher refractive indices (>2.0), the optical nonlinearities and transmission at longer wavelengths in the infrared region.…”

“…Although these glasses are considered to be promising materials for use in all-optical devices, it is required for them to possess high thermal stability, excellent surface polishing properties, high refractive index, etc. [2,[12][13][14]. It is therefore important to carefully prepare and measure the density, glass transition temperature (T g ) values and calculate N 4 (BO 4 / (BO 3 + BO 4 )) from IR spectra in these technologically important materials.…”

Absorption and fluorescence studies of Sm3+ ions in lead containing sodium fluoroborate glasses

“…Borate glasses show clear relationship between glass structure and physical properties, high transparency, low melting point, high thermal stability and good glass forming nature have been identified as more useful host matrices to accommodate the required quantity of rare earth ions compared to several other conventional glassy systems [2][3][4]. Borate glasses incorporated by heavy metal oxides can give intense fluorescence in the visible spectral region which is used as electro-optic modulators, electro-optic switches, solid-state laser materials and non-linear parametric converters [5][6][7][8].…”

Emission analysis of RE3+ (Eu3+, Tb3+ & Ho3+): B2O3-BaO-LiF/AIF3 glasses

“…In recent years, a special interest has been focused towards the production of fluoro-borate glasses because of their potential applications as luminescent materials [10][11][12]. It is interesting to mention that these borate glasses having boron-oxygen groups which could be dominantly contributing in luminescence phenomenon thus these glasses have been identified as potential optical materials for their use in optoelectronics.…”
