Efficient 2 µm emission in Nd3+/Ho3+ co-doped silicate-germanate glass pumped by common 808 nm LD
Nd 3+ /Ho 3+ co-doped silicate-germanate glass has been synthesized by high temperature melt-quenching method. Near infrared emission centered at 2 µm has been successfully obtained by incorporating Nd 3+ and Ho 3+ in present glass. The Judd-Ofelt intensity parameters Ω t (t=2, 4, 6), and radiative properties of Ho 3+ were calculated and discussed by using the Judd-Ofelt theory. The energy transfer processes and luminescence properties of Nd 3+ /Ho 3+ co-doped glasses were analyzed pumped by a conventional 808 nm laser diode . Desirable spectroscopic characteristics indicates that Nd 3+ /Ho 3+ co-doped silicate-germanate glass might be a good alternative matrix for 2 µm band mid-infrared laser.
