Lead carbonate chloride, Pb2CO3Cl2, known as mineral phosgenite, is introduced as a novel SRS-active carbonate crystal with tetragonal symmetry. Under picosecond one-micron laser pumping Raman-induced χ(3)-nonlinear generation in the near-IR is observed. All recorded high-order Stokes and anti-Stokes sidebands are identified and attributed to two SRS-promoting vibration modes with ωSRS1 ≈ 1062 cm–1 and ωSRS2 ≈ 86 cm–1.

Alexander A. Kaminskii, Ladislav Bohatý, Hanjo Rhee, André Kaltenbach, Oliver Lux, Hans J. Eichler, Reinhard Rückamp and Petra Becker (2013): Cerussite, PbCO3 - a new Stimulated Raman Scattering (SRS)-active crystal with high-order Stokes and anti-Stokes lasing. Laser Photonics Rev. 7, 425-431.

Orthorhombic PbCO3, known as natural crystal cerussite, is presented as a new Stimulated Raman Scattering (SRS)-active crystal. With picosecond laser pumping high-order Raman-induced χ(3) generation is observed. All registered Stokes and anti-Stokes sidebands in the visible and near-IR are identified and attributed to the SRS-promoting phonon mode A1g of the carbonate group, with ωSRS ≈ 1054 cm−1. The first Stokes steady-state Raman gain coefficient in the visible spectral range is estimated as well to a value not less than 4.6 cm•GW−1.
