•We compute the ABCD matrix for parabolic mirrors valid under paraxial approximation.•An expression for any incident angle for on/off axis parabola is obtained.•We use it to simulate a four-mirror cavity made of two parabolic mirrors.•A procedure to align such cavity is proposed and studied numerically.
The ABCD matrix for parabolic reflectors is derived for any incident angles. It is used in numerical studies of four-mirror cavities composed of two flat and two parabolic mirrors. Constraints related to laser beam injection efficiency, optical stability, cavity-mode, beam-waist size and high stacking power are satisfied. A dedicated alignment procedure leading to stigmatic cavity-modes is employed to overcome issues related to the optical alignment of parabolic reflectors.
