“…The pump laser operated at 0.2 Hz. The experiment confirmed the conclusion made in [41] that liquid nitrogen cooling would be required for laser action. In the absence of the intracavity prism, the lasing wavelengths were 5.7-5.85 µm, depending on the cavity Q-factor.…”

“…strong overlapping of the Tb 3+ luminescence spectra with the absorption band of Nd 3+ corresponding to the 4 I11/2 level and investigated the energy transfer between these ions. Our investigation [41] showed that a Tb 3+ →Nd 3+ energy transfer takes place indeed, but at room temperature, it is reversible and cannot provide the high Nd 3+ 4 I11/2 population required for laser action. Nevertheless, at the liquid nitrogen temperature, the Tb 3+ →Nd 3+ energy transfer becomes unidirectional and suitable for Nd 3+ mid-infrared lasing.…”

This paper provides an overview of mid-infrared lasers based on rare-earth-ion-doped selenide glasses. Laser action was demonstrated at the transitions between the first excited and the ground levels of Ce3+, Pr3+, Nd3+ and Tb3+ ions. The highest output parameters for bulk glass lasers (over 40 mJ of output energy) and wavelength tuning in the range of 4.6–5.6 microns were obtained with Ce3+-doped glass. The highest output parameters for fiber lasers (150 mW at 5.1–5.3 μm under continuous pumping) were demonstrated with Tb3+ ions. The longest lasing wavelengths for any glass laser and tunability within the 5.56–6.01 µm spectral band were shown with Nd3+ ions in a Tb3+-Nd3+ co-doped system.
