Near-infrared luminescence properties of Nd and Ho ions in barium gallo-germanate glasses have been reported. Several spectroscopic parameters for Nd and Ho ions have been determined from the Judd-Ofelt analysis and absorption/luminescence measurements. Quite large luminescence lifetime, quantum efficiency and stimulated emission cross-section have been obtained for the main F → I (Nd) and I → I (Ho) laser transitions of rare earths in barium gallo-germanate glasses. It suggests that barium gallo-germanate glass is promising for near-infrared laser application at emission wavelengths 1064 nm (Nd) and 2020 nm (Ho).

In the framework of luminescent rare-earth-doped glasses for near-infrared applications, TiO-containing inorganic glasses have been recently demonstrated to be a promising alternative to commercially used high-phonon SiO-based glasses. This study investigates the effect of TiO concentration on the near-infrared spectroscopic properties of Yb ions in multicomponent titanate-germanate glasses. A series of glass samples in the xTiO-(60-x)GeO-BaO-GaO-YbO system (x ranging from 0 to 50 mol%) were synthesized using the melt-quenching technique.

We demonstrate a GHz repetition rate mode-locked Tm-doped fiber laser with low noise. Based on a home-made Tm-doped barium gallo-germanate fiber with reduced dispersion, a broad optical spectrum of mode-locking is achieved, and its amplified spontaneous emission quantum-limited timing jitter is largely suppressed. Besides, we carefully investigate the influence of the intracavity pump strength on the noise performance of the mode-locked pulses and find that manipulating the intracavity pump power can be an effective method for optimizing the timing jitter and relative intensity noise (RIN).

We report on direct femtosecond laser writing in zinc barium gallo-germanate glasses. A combination of spectroscopic techniques allows to progress in the understanding of the mechanisms taking place depending on the energy. In the first regime (type I, isotropic local index change) up to 0.

Modified barium gallo-germanate glass hosts are still worthy of attention in studying structure-property relationships. In this work, two different series of glass systems based on (60-x)GeO-xTiO-30BaO-10GaO and (60-x)GeO-xBO-30BaO-10GaO (x = 10, 30, 50 mol%) were synthesized, and their properties were studied using spectroscopic techniques. X-ray diffraction (XRD) patterns revealed that all fabricated glasses were fully amorphous material.
