Abstract

The polarization dependence of the Lamb coupling constant C between the polarization eigenmodes of a spin-VECSEL is experimentally studied. A spatial separation of 20 µm between the two eigenmodes in the active medium is set up to artificially decrease C and allow a robust simultaneous oscillation of the two eigenmodes, thus making measurable a slight change of C . The value of C turns out to be polarization-dependent. Indeed, a value of C =0.70±0.03 for circular polarizations versus C =0.86±0.03 for linear polarizations is found, corresponding, respectively, to C =0.97±0.04 and C =1.19±0.04 when the two eigenmodes are superimposed in the active medium.
