Highly efficient cascaded amplification using Pr(3+)-doped mid-infrared chalcogenide fiber amplifiers.
We computationally investigate cascaded amplification in a three-level mid-infrared (IR) Pr(3+)-doped chalcogenide fiber amplifier. The overlap of the cross-sections in the transitions (3)H(6)→(3)H(5) and (3)H(5)→(3)H(4) enable both transitions to simultaneously amplify a single wavelength in the range between 4.25 μm and 4.55 μm. High gain and low noise are achieved simultaneously if the signa...
متن کاملPr3+ doped CoFe2O4: A highly efficient, magnetically recoverable and reusable catalyst for one-pot four-component synthesis of multisubstituted pyrroles
A facile and highly efficient one-pot synthesis of multisubstituted pyrrole derivatives is reported via a four-component reaction of amines, aldehydes, acetylacetone and nitromethane using Pr3+ doped CoFe2O4 as a catalyst in solvent free conditions at 90°C. The catalyst is easily recoverable using magnet and could be reused without a significant loss of catalyti...

متن کاملTm3+-doped CW fiber laser based on a highly GeO2-doped dispersion-shifted fiber.
A novel all-fiber laser based on a highly GeO2-doped dispersion-shifted Tm-codoped fiber, pumped at 1.56 µm wavelength and lasing at 1.862 µm wavelength with a slope efficiency up to 37% was demonstrated. The single-mode Tm-doped fiber with the 55GeO2-45SiO2 core was fabricated for the first time by MCVD technique. The laser produces spectral side bands, resulting from the four-wave mixing owin...
متن کاملEfficient linearly polarized ytterbium-doped fiber laser at 1120 nm.
We report a 20 W linearly polarized, spectrally clean Yb-doped fiber laser at 1120 nm with an optical conversion efficiency of 54%. An excellent polarization extinction ratio of more than 23 dB is obtained using fiber Bragg gratings (FBGs) polarization selection technique at all power levels. The results reveal that a Yb-doped fiber laser at 1120 nm could be a promising replacement compared to ...
