Spectral properties of Er3+-doped CaGdAlO4 crystal for laser application around 1.55μm

Thermal, Spectral and Laser Properties of Er3+:Yb3+:GdMgB5O10: A New Crystal for 1.5 μm Lasers

“…Then the oscillator intensity parameters Ω t , transition probability A, fluorescence branching ratio β and radiative life time τ rad were calculated. The detailed calculating process follows those of Reference [22,23]. The results are listed in Table 1 and Table 2.…”

Crystal growth, first-principles calculations, and enhanced 1.5–1.7 μm fluorescence emission from the Er, Ce: CaGdAlO4 laser crystal

“…Huang et al found that Er: CGA crystals have a large emission cross-section and a broad emission band at 1.5–1.7 μm, which can be considered a potential gain medium for low-threshold lasers around 1.55 μm. 24 In our previous study, the doping concentration of Er 3+ most favorable for 1.5 μm luminescence was 5% in Er: CGA crystals. 25 Fig.…”

“…19,20 Its multiple structural disorders and excellent optical and thermal properties make the CGA crystal stand out among the many crystals with disordered structures. Currently, Tm: CGA, 21,22 Nd: CGA, 23 and Er: CGA 24,25 crystals have been shown to be potential laser crystals at relevant wavelengths. Yb: CGA, 26 Nd: CGA, 27 and Tm: CGA 28 crystals have achieved laser outputs at 1048 nm, 1079 nm, and 1938 nm, respectively.…”
