Tm3+ and Tm3+-Ho3+ doped fluorogermanate glasses for S-band amplifiers
چکیده انگلیسی
Two series of glasses with composition (mol%) 70PbGeO3-15PbF2-15CdF2, the first one with different Tm3+ contents (0.2, 0.4, 0.6 and 0.8 mol%) and the second one with 0.2 mol% Tm3+ and different Ho3+ contents (0.1, 0.5, 1.0 and 1.5 mol%), have been prepared and some of their spectroscopic properties studied. Absorption in the visible-near infrared and emission in the near infrared region of the electromagnetic spectrum have been obtained. Concerning emission at the 1.4-1.5 μm region, optimization of rare earth ions content leads to 0.2 and 0.5 mol% for Tm3+ and Ho3+, respectively. We discuss potential application of these compositions.
