[PROBLEMS] To perform simultaneous automatic adjustment of the position and angle of an optical axis (two purposes), An automatic optical axis adjusting device for automatically adjusting a position and an angle deviation of an optical axis of a laser beam, wherein at least two optical axis adjusting mirrors installed on an optical path of the laser beam, A control mechanism provided with at least two mirrors, one or two optical axis detection sensors for detecting the position and angle of the optical axis with the same or different sensors, and a controller for driving the control mechanism based on a light reception signal from the sensors. An optical axis automatic adjustment apparatus that includes an adjustment device that outputs a control signal, and that outputs the control signal so as to obtain a plurality of Pareto optimal solutions related to the position and angle of the optical axis according to a multi-objective optimization method.
