    Opis:
    In the paper the application of multicore optical fibres in phased-locked high power lasers is presented. The manufacturing and properties of multicore active optical fibres were presented. The thermally stable aluminosilicate glass doped with $Nd^{3+}$ (0.5 mol%) ions were melted and used as cores in manufactured multicore optical fibres. Two configurations of double clad multicore optical fibres with the circular array containing 15 and 30 $Nd^{3+}$ doped cores on ring inside a large pump clad were realized. Absorption and luminescence spectra of obtained glasses and fibres were presented. An external plane mirror located at certain distance of the array forms the basic Talbot cavity. The possibilities of mode selection and phase-locking by using Talbot resonator applied to fabricated multicore fibres were investigated.

    Opis:
    In the article there are presented two different series of glass: fluorophosphate with molar composition: $65P_2O_5-8Al_2O_3-$ $2BaO-5BaF_2-6ZnF_2-$ $5Na_2O-$ $6MgF_2-3B_2O_3$ and antimony glasses $40Sb_2O_3-$ $3Al_2O_3-$ $57SiO_2$ doped with $Nd^{3+}$ and $Yb^{3+}$ ions. Dopant contents influence efficient spatial overlapping of emission level for neodymium and absorption level for ytterbium was analyzed. While exciting the produced glasses with a laser diode (λ = 808 nm) a broad luminescence spectrum (Δλ = 100 nm) has been obtained in both cases in the vicinity of 1 μm, being the superposition of the following transitions: $\text{}^4F_{3//2} \rightarrow {\text{}^4I_{11//2}}$ for $Nd^{3+}$ and $\text{}^2F_{5//2} \rightarrow {\text{}^2F_{7//2}}$ for $Yb^{3+}$. Based on the luminescence measurements the probability of non-radiative energy transfer was described. Because of a small difference in energy ( ≈1190 $cm^{-1}$) between the laser levels of neodymium and ytterbium the resonant process of energy transfer has been obtained.

    Opis:
    The paper presents luminescence properties of telluride glass doped with $Yb^{3+}//Tm^{3+}$ ions. Strong blue emission at 477 nm corresponding to the transition $\text{}^1 G_4 \rightarrow \text{}^3 H_6$ in thulium ions was measured under the excitation of a 976 nm diode laser. The dependence of the upconversion emission upon the thulium ions concentration was studied in order to determine the optimal ion content. The results showed that intensity of upconversion emission enhances, with the increase of $Tm^{3+}$ content up to 0.1 mol.%. The most effective energy transfer $Yb^{3+} \rightarrow Tm^{3+}$ occurs in the glassy matrix with molar ratio of dopant 1 $Yb^{3+}$ : 0.1 $Tm^{3+}$. Double-clad optical fibre was made of glass with the highest upconversion intensity at the wavelength of λ = 477 nm (TGPF101). As a result of optical excitation (λ = 976 nm) of the produced optical fibre, an additional emission line, which was not noticed in the glass, was observed at the wavelength of 351 nm corresponding to the $\text{}^1 D_2 \rightarrow \text{}^3 H_6$ transition.

    Opis:
    In the paper the spectroscopic properties of antimony-germanate glass co-doped with $Yb^{3+}//Ho^{3+}$ has been investigated. Fabricated $Yb^{3+}//Tm^{3+}/Ho^{3+}$ co-doped glass is characterised by the emission of simultaneous multicolour upconversion luminescence. Strong blue $\text{}^{1}G_{4} \rightarrow \text{}^{3}H_{6}(Tm^{3+})$, green $\text{}^{5}F_{4} \rightarrow \text{}^{5}I_{8}(Ho^{3+})$ and red $\text{}^{5}F_{5} \rightarrow \text{}^{5}I_{8}(Ho^{3+})$ upconversion emission bands have been measured under 976 nm excitation at room temperature. Influence of molar ratio of active ions and excitation power on the colour coordinates (CIE-1931) have been investigated.
