We demonstrate the polarization-dependent laser oscillation of a biphenyl-capped thiophene crystal based on stimulated resonance Raman scattering (SRRS) at room temperature. Under optical excitation at resonant absorption wavelengths, a platelet single crystal shows amplified spontaneous emission (ASE) with a full width at half maximum (FWHM) of ∼5 nm. This ASE intensity is increased at the polarization perpendicular to the crystal face [i.e., transverse magnetic (TM) mode]. When excitation wavelengths approach the absorption edge, the single crystal emits a pair of further narrowed emission lines (FWHM < 0.5 nm) due to a transition into the SRRS regime. The intensity of the SRRS line at 1455 cm-1 is selectively increased at the polarization parallel to the crystal face [i.e., transverse electric (TE) mode]. On the other hand, the SRRS line at 1596 cm-1 is propagated in the TM mode. This polarization-dependent SRRS phenomenon is related to the coherent molecular vibrations in the uniaxially oriented single crystal.
