Stimulated Raman scattering of the second harmonic of a neodymium laser in nitrate crystals

Frequency shift and vibronic relaxation of Raman modes in barium nitrate molecular ionic crystal

“…Recently, the increase of the research on developing solid state Raman lasers has been observed. 1-3 For a constant pump field, the Stokes field grows exponentially with a power gain given by: (1) where G is the Raman gain coefficient and 1 is the propagation length in the Raman medium. In terms of spontaneous Raman scattering cross-section, dci/dt2, the gain coefficient G can be obtained as following: G = 2N(d%Q)I (2) flhC7CAQR where 2, and 2 are the pump and stokes wavelengths, 4 is the pump intensity, N is the density of scattering centers and Lq is the full-width at half maximum (FWHM) of the Raman line.…”

Laser crystals and ceramics: recent advances

“…The investigation of SRS in crystalline solids (it is likely that natural diamond and calcite were used) dates from 1963 [304]. The first known SRS-active synthetic crystals were orthorhombic α-sulphur [304], polar niobates LiNbO 3 and Ba 2 NaNb 5 O 15 [308], α-LiIO 3 [312], and centrosymmetric nitrates Ba(NO 3 ) 2 , NaNO 3 , and Pb(NO 3 ) 2 [357]. The discovery of SRS potential in several widely used insulating laser host crystals (e.g.…”

Attainment of growth stability through the widening of Ostwold–Mier's zone width: A novel technique

“…Since then SRS in solids has become an area of intensive investigation in laser physics. Eremenko et al [2] have proposed the barium nitrate Ba(NO 3 ) 2 as a potential SRS material. Barium nitrate crystal has cubic symmetry with cell parameter a = 8.11Å, z = 4 and belongs to P213 space symmetry group [3].…”
