A gas absorption spectroscopy system includes a resonator, a light source, a driver, a controller, and a detector. The resonator includes a first mirror and a second mirror. The light source irradiates the resonator with laser light. The driver varies a length between the first and second mirrors. The controller controls the driver. The detector outputs to the controller a detection signal corresponding to the detected light. The driver moves at least one of the first and second mirrors about a sweep center to change the length between the first and second mirrors, and, in response to the controller obtaining the detection signal, adjusts a length between the sweep center and the second mirror to be equal to a length present between the first and second mirrors at a time when the detection signal is obtained.
