Abstract

Abstract : Tetragonal polar barium antimony tartrate is introduced as a new SRS‐active crystal with a large Raman shift of ∼2940 cm −1 . The crystals allow to convert one‐micron laser radiation into the eye‐safe wavelength region. Abstract : The non‐centrosymmetric polar tetragonal ( P 41 ) barium antimony tartrate trihydrate, Ba[Sb2 ((+)C4 H2 O6 )2 ]·3H2 O, was found to be an attractive novel semi‐organic crystal manifesting numerous χ (2) ‐ and χ (3) ‐nonlinear optical interactions. In particular, with picosecond single‐ and dual‐wavelength pumping SHG and THG via cascaded parametric four‐wave processes were observed. High‐order Stokes and anti‐Stokes lasing related to two SRS‐promoting vibration modes of the crystal, with ωSRS1 ≈ 575 cm −1 and ωSRS2 ≈ 2940 cm −1, takes place. Basing on a spontaneous Raman investigation an assignment of the two SRS‐active vibration modes is discussed.
