Glass-Ceramics with Co:Ga2O3 Nanocrystals: A Saturable Absorber for 1.5-1.7 μm Erbium Lasers

Transparent glass-ceramics containing γ-Ga2O3:Co2+ nanocrystals are synthesized in the lithium gallium silicate system. The observed red-shift of the absorption band related to the 4A2g(4F)→4T1g(4F) transition of Co2+ ions in tetrahedral sites and absorption saturation properties indicate that the g...

Summary:Transparent glass-ceramics containing γ-Ga2O3:Co2+ nanocrystals are synthesized in the lithium gallium silicate system. The observed red-shift of the absorption band related to the 4A2g(4F)→4T1g(4F) transition of Co2+ ions in tetrahedral sites and absorption saturation properties indicate that the glass-ceramics is suitable for the Q-switching of 1.5-1.7 μm eye-safe erbium lasers. Passively Q-switched Er,Yb:glass diode-pumped laser delivering 1.75 mJ of 25 ns-long pulses at 1540 nm is realized.
