Multiphoton SRS-Lasing in a Monoclinic beta-BaYb2F8 Crystal

摘要

The discovery of stimulated Raman scattering (SRS) in monoclinic fluoride beta-BaYb2F8 known as a host matrix for Ln(3+) lasant ions was reported. All the recorded spectral components of Stokes and anti-Stokes chi ((3))-nonlinear picosecond generation were assigned to the three SRS-active photon A (g) - and B (g) -modes of a crystal (omega(SRS1) - 362 cm(-1), omega(SRS2) - 295 cm(-1), and omega(SRS3) - 230 cm(-1)).
