“…In this work, we demonstrate the Q-switching operation in Yb-doped fiber lasers (YDFL) based on Mo 0.5 W 0.5 S 2 SAs. The Mo 0.5 W 0.5 S 2 is fabricated by microwave-assisted solvothermal method (MAST) [26] and its polymer film is inserted into the fiber cavity. Gradually increasing the pump power, stable Q-switched pulses are obtained.…”

In this work, we fabricate the MoWS by microwave-assisted solvothermal method, and report the Q-switched Yb-doped fiber lasers (YDFL) using MoWS polymer film and tapered fiber as the saturable absorbers (SAs). The modulation depth and saturable intensity of the film SA are 5.63% and 6.82 MW cm. The shortest pulse duration and the maximum single pulse energy are 1.22 μs and 148.8 nJ for the film SA, 1.46 μs and 339 nJ for the fiber-taper SA. To the best of our knowledge, this is the first report on the Q-switched YDFL using MoWS SAs.

“…12 It was also shown that by varying the temperature, pressure and duration of the MAH process as well as the pH of the initial solution, one can signicantly inuence the product morphology and physicochemical properties. [13][14][15] The aim of the present study is to evaluate microwaveassisted hydrothermal synthesis (MAH) as a preparation technique of Lu 4 Hf 3 O 12 :Pr powders and to characterize their luminescence properties. Thus, the inuence of the process parameters, pH of the solution and composition of the solvent on the morphology of the Lu 4 Hf 3 O 12 :Pr powders as well as their optical characteristics is discussed in detail.…”

Exclusively high density of Lu 4 Hf 3 O 12 makes it an attractive host for scintillator materials. This paper presents the versatility of microwave-assisted hydrothermal technology (MAH) to fabricate nanocrystalline Lu 4 Hf 3 O 12 :Pr luminescent powder. It is shown that by varying the parameters of the fabrication procedure, changing the composition of the liquid medium and/or using polyethylene glycol, PEG 2000, as a surfactant, the morphology of the powders could be modified. In the presence of PEG, obtaining non-agglomerated particles $5 nm in diameter was possible. Sintered ceramics at 1700 C were fabricated using various powders. Photoluminescence and X-ray excited emission spectra showed the Pr 3+ emission resulting from 4f / 4f transitions. At room temperature the 3 P 0 and 1 D 2 levels contributed roughly equally to the total emission in both the powders and sintered ceramics. The former produced luminescence with a decay time of $15 ms while the latter was an order of magnitude slower. At 10 K the emission resulted almost exclusively from the 3 P 0 level. In addition, a broad-band blue luminescence was observed at low temperatures. Room temperature radioluminescence (RL) was found to be rather inefficient in both the powders and ceramics.
