Optical-axis perturbation in triaxial ring resonator

Abstract

We report several findings on the optical-axis perturbation of monolithic triaxial ring resonator. A criterion, C, which represents the mismatching error of the monolithic triaxial ring resonator, has been found out and it cannot be decreased by modifying the angles of the terminal surfaces or the terminal mirrors of the resonator. When C not equal 0, an optimization method to share the mismatching error C in some specific directions equally and simultaneously has been proposed. The interesting findings are important to cavity design, cavity improvement, and alignment of the monolithic triaxial ring resonator.

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

“…The mirror's misalignment-induced optical-axis perturbations in square ring resonator and traxial ring resonator has been discussed in our previous article [1,14,15]. The spherical mirror's axial-displacement are the main perturbation source in our following discussion.…”

“…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].…”

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].…”

空间三轴环形谐振腔综合失谐误差的消除方法

“…2 [1] , a spherical mirror has been chosen as an example to show the perturbation sources. M and M represent the mirrors before and after axial displacement δ along the normal z direction.…”

“…2 [1] , the axial displacement of the mirror influences ray transfer. When the spherical mirror has a small axial displacement δ along the z axis, the reflection point changes from P 1 to P 2 .…”
