Optical-axis perturbation in triaxial ring resonators II: induced by spherical mirror's axial displacement

Abstract

Abstract：The augmented 5×5 ray matrix with the consideration of spherical mirror's axial displacement has been proposed in this article. By applying it to a planar square ring resonator and a monolithic triaxial ring resonator, the optical-axis perturbation induced by spherical mirror's axial displacement has been obtained. The mismatching error C of the monolithic triaxial ring resonator has been found out that it can be decreased and can be even reduced to 0. These interesting findings are important to cavity design, cavity improvement and alignment of monolithic triaxial ring resonator. This is a continue paper of ref [1]. There has been extensive research on optical-axis perturbation in those ring resonators including triangular ring resonator, square ring resonator, folder planar ring resonator, nonplanar ring resonator and triaxial ring resonator [2][3][4][5][6][7][8][9][10][11][12][13][14][15].However, the perturbation sources in all the previous articles are radial displacements or angular misalignments of the optical components of the ring resonator. The perturbation source of the mirror's axial displacement has not been discussed before. The augmented 5×5 ray matrix Laser Resonators and Beam Control XII, edited

Generalized model for beam-path variation in ring resonator and its applications in backscattering coupling effect

“…Optical-axis perturbation of monolithic triaxial ring resonators has also been discussed in previous articles [18][19][20][21]. In summary, the optical-axis perturbation in planar or nonplanar ring resonators has been discussed extensively [10][11][12][13][14][15][16][17][18][19][20][21].…”
