摘要: We report the first observation of tunable stimulated Raman emission. A Q‐switched ruby laser was used to excite A1 symmetry 248‐cm−1 polariton mode in a LiNbO3 crystal. The crystal, at room temperature, placed resonator external cavity which tuned Stokes frequency. It possible vary frequency by altering angle between pump beam and axis resonator. Stimulated scattering from other modes (152 cm−1, 628 cm−1) are potentially observed. also anti‐Stokes emission mode.
