NIR Luminescence From Nd3+ And Er3+ Ions Doped Cadmium Borate Glasses For Optical Amplification

In this paper, we report the near‐infrared luminescence from the Nd3+ and Er3+ ions doped cadmium borate glasses for optical amplification. The absorption and luminescence spectra of the host glass matrix have been carried out at room temperature. From these spectra, Judd‐Ofelt intensity and laser parameters have been computed and discussed. The NIR spectra of Nd3+ and Er3+ ions doped glasses have shown full‐width at half maxim (FWHW) around 19, 21, 22 and 24 nm respectively. These glasses have potential applications in broadly tunable laser sources and broadband optical amplification at low‐loss telecommunication windows.
