Low threshold Er/Yb

چکیده
[email protected] An Erbium:Ytterbium codoped microcavity-based laser which is lithographically fabricated from sol-gel is demonstrated. Both single-mode and multimode lasing is observed in the C band (1550nm). The quality factor and pump threshold are experimentally determined for a series of erbium and ytterbium doping concentrations, verifying the interdependent relationship between the two dopants. The lasing threshold of the optimized device is 4.2 W.

High upconversion quantum yield at low pump threshold in Er3þ/Yb3þ doped La2O2S phosphor
In this letter, we report the absolute upconversion quantum yields (QY) for 9% Yb3þ and 1% Er3þ codoped La2O2S and its comparison with NaYF4 doped with 20% Yb 3þ , 2% Er3þ for all the upconversion emissions centered at 410, 550, 667, and 822 nm at various excitation power densities at 977 nm excitation. The maximum upconversion QY for 9% Yb3þ and 1% Er3þ co-doped La2O2S was measured to be 5.837...
متن کاملAlpha induced reaction cross section measurements on 162Er for the astrophysical γ process
a r t i c l e i n f o a b s t r a c t The cross sections of the 162 Er(α, γ) 166 Yb and 162 Er(α, n) 165 Yb reactions have been measured for the first time. The radiative alpha capture reaction cross section was measured from E c.m. = 16.09 MeV down to E c.m. = 11.21 MeV, close to the astrophysically relevant region (which lies between 7.8 and 11.48 MeV at 3 GK stellar temperature). The 162 Er(...
متن کاملYb 3 + codoped NaMnF 3 nanocubes with single - band red upconversion luminescence †
Wehave developed a facile low-temperature synthetic method for the preparation of NaMnF3 nanocubes with Er 3+ and Yb ions homogeneously incorporated in the host lattice. The effects of the reaction temperature, and the volume ratio between ethanol and DI water on themorphology of NaMnF3 nanocubes are systematically investigated. The NaMnF3 nanocubes can be produced in the low temperature range ...
متن کاملEfficient upconversion luminescence from Ba5Gd8Zn4O21:Yb(3+), Er(3+) based on a demonstrated cross-relaxation process.
Under 971 nm excitation, bright green and red emissions from Yb(3+)/Er(3+) co-doped Ba5Gd8Zn4O21 phosphor can be observed, especially the intense red emission in highly doped samples. The experimental results indicate that Ba5Gd8Zn4O21:Yb(3+), Er(3+) emits stronger upconversion luminescence than NaYF4:Yb(3+), Er(3+) under a low excitation power, and a maximum upconversion power efficiency of 2....
متن کاملEvaluation of spectroscopic properties of Er3+/Yb3+/Pr3+: SrGdGa3O7 crystal for use in mid-infrared lasers
Er(3+)/Yb(3+)/Pr(3+): SrGdGa3O7 crystal was firstly grown by Czochralski method. Detailed spectroscopic analyses of Er(3+)/Yb(3+)/Pr(3+): SrGdGa3O7 were carried out. Besides better absorption characteristic, the spectra of Er(3+)/Yb(3+)/Pr(3+): SrGdGa3O7 show weaker up-conversion and near-infrared emissions as well as superior mid-infrared emission in comparison to Er(3+): SrGdGa3O7 and Er(3+)/...
