Amplitude and phase noise sensitivity of modelocked Ti:sapphire lasers in terms of a complex noise transfer function

Abstract: The amplitude and envelope phase noise of a modelocked laser are shown to depend directly on the pump laser amplitude stability. We characterize the sensitivity of this process by a noise transfer function which represents the complex amplitude-to-amplitude modulation (AM-AM) and amplitude-to-phase modulation (AM-PM) conversion gain of the pump-induced amplitude and phase noise, respectively. We find that a linearized laser model extrapolated from relaxation oscillation theory, combined with a thermal model, adequately describe the principal features of the response from <1 Hz to 10 MHz.

Electronic state of a conducting single molecule magnet based on Mn-salen type and Ni-dithiolene complexes

Abstract: The electrochemical oxidation of an acetone solution containing [MnIII (5-MeOsaltmen)(H2O)]2(PF6)2 (5-MeOsaltmen2– = N,N′-(1,1,2,2-tetramethylethylene)bis(5-methoxysalicylideneiminate)) and (NBu4)[Ni(dmit)2] (dmit2– = 2-thioxo-1,3-dithiole-4,5-dithiolate) afforded a hybrid material, [Mn(5-MeOsaltmen)(acetone)]2[Ni(dmit)2]6 (1), in which [Mn2]2+ single-molecule magnets (SMMs) with an ST = 4 ground state and [Ni(dmit)2]n− molecules in a charge-ordered state (n = 0 or 1) are assembled in a layer-by-layer structure. Compound 1 crystallizes in the triclinic space group P1 with an inversion center at the midpoint of the Mn···Mn dimer. The [Mn2]2+ unit has a typical nonplanar Mn(III) dimeric core and is structurally consistent with previously reported [Mn2] SMMs. The six [Ni(dmit)2]n− (n = 0 or 1) units have a square-planar coordination geometry, and the charge ordering among them was assigned on the basis of ν(C═C) in IR reflectance spectra (1386, 1356, 1327, and 1296 cm–1). The [Mn2]2+ SMM and [Ni(dmit)2]n− u...

Experimental Study on the Criticality of a Methane/Ethane Mixture Confined in Nanoporous Media.

Abstract: For the first time, the critical region of a methane/ethane mixture confined in nanoporous media (SBA-15) is experimentally investigated using differential scanning calorimetry with an isochoric co...
