✦ Synopsis

Efficient room-temperature Stokes and anti-Stokes χ (3) -nonlinear picosecond generation, which spans more than two octaves (≈ 23012 cm -1 ) has been observed in a natural crystal of orthorhombic SrSO 4 (celestine). All recorded lasing lines in the visible and near-IR regions are identified and attributed to its SRS-promoting vibration mode ω SRS ≈ 999 cm -1 .

We report on the first observation of stimulated Raman scattering (SRS) in cubic SrF2. All recorded high-order Stokes and anti-Stokes lasing sidebands in the visible and near-IR (up to the 28th order) are identified to the single SRS-promoting vibration mode of the crystal with ω ≈ 282 cm -1 .

We report new laser and nonlinear-laser properties of Nd 3+ -ion doped and undoped orthorhombic calcium niobate. In particular, we show that: Nd 3+ :Ca(NbO 3 ) 2 is a promising gain medium for LD-pumped microchip lasers and undoped Ca(NbO3)2 can give rise to high-order lasing covering more than two-
