Dependence of properties of optical cavity on misalignment
Abstract
The effect of misalignment in an optical cavity with plane mirrors and focusing lens on its properties is analyzed in the parallax approximation with the aid of (ab/cd) ray matrices, considering that the principle consequence of misalignment between the resonator components is a change in the length of its optical axis. The resultant ray matrix is obtained as the product of three 4x4 matrices multiplied in the reverse order in which a ray passes through these elements: matrix of translation through distance L (length of the optical axis), matrix of astigmatic lens with principal focal lengths f(x),f(y) and matrix of reflection by a plane mirror. This general method is applied, for illustration, to a ring cavity with an even number of mirrors and a planar axial contour.
