摘要
A method for determining stabilization of a light output signal employed by a laser frequency stabilizing device which irradiates laser light on an absorption cell to obtain the light output signal and, based on a saturated absorption line contained in the light output signal, changes a resonator length to stabilize an oscillation frequency of the laser light to a specific saturated absorption line. The laser frequency stabilizing device includes a conversion mechanism converting the laser light that passes through the absorption cell into the light output signal, an actuator changing the resonator length, and a control mechanism controlling operation of the actuator. The method for determining stabilization includes a signal analysis step analyzing the light output signal and a stabilization determination step determining whether the light output signal is stabilized based on an analysis result from the signal analysis step, executed by the control mechanism.
