ABSTRACT:
The present invention is a laser (12) having a resonator (28) between an output coupling mirror (20) and a high-reflection mirror (26). A photoelastic plate (38) is incorporated in a photoelastic cell (24), or a photoelastic mirror (36) used in place of the high-reflection mirror (26). The photoelastic plate (38) is placed in the resonator (28) and introduces an artificial anisotropy to the laser (12). The photoelastic plate (38) has privileged directions (34), which are aligned with the axes of the artificial anisotropy. A magnetic field (32) is applied transversely to the resonator (28), in alignment with one of the privileged directions (34), to produce two orthogonal linearly polarized frequencies in an output beam (30) with the Zeeman effect.
