Abstract

To enhance the correlation in the orthogonal directions, a polarization self-modulation scheme with an intra-cavity quarter wave plate in a coaxial pumping orthogonally polarized laser was proposed. This quasi-isotropic cavity was compared with the traditional scheme in terms of the differences in the oscillation between dual components and the intra-cavity eigenstate distribution was obtained. Both theoretical and experimental results indicated that modes were effectively locked in TE and TM directions and dual-eigenstates output was achieved, which provided a half-free-spectrum-range frequency difference in ±45° directions. Q-switching and dual-wavelength-operation did not affect the polarization self-modulation process.
