A 156cm–1 red-shift is gained theoretically to demonstrate the presence of non-neglectable weak H-bonds and result in the discovery of the rarely reported trimeric H-bond, which consists of three independent hydroxyl donors and only one Cl– acceptor, in the field of crystal materials. We explained the relative weakness of this kind of hydrogen bond which may have a critical effect on the lattice symmetry and magnetic structure.

To meet the needs, a novel low-noise fiber laser with compound cavity structure is designed. The stable single-mode operation is realized by using a transient self-written fiber grating, produced by the effect of saturable absorption within a section of unpumped erbium-doped fiber, as narrow band filter for mode selecting and linewidth squeezing. Through optical path modification, the spectral signal-to-noise ratio is better than 62 dB.
