Abstract:
A laser device includes an excitation light source, a resonator which receives excitation light from the excitation light source and generates laser light, an absorption cell to which the laser light is emitted, a light converter which converts the laser light passing through the absorption cell to a light output signal, a third order differential lock-in amplifier which generates a third order differential signal of the light output signal, and a controller. When a predetermined waveform of the third order differential signal is detected, the controller includes a return controller that determines a return direction of a resonator length based on the predetermined waveform and a resonator length controller that changes the resonator length to the return direction.

Claim (Index 3):
A laser stabilizing method employing a laser device that comprises an excitation light source; a resonator which receives excitation light from the excitation light source and generates laser light; an absorption cell to which the laser light is emitted; a light converter which converts the laser light passing through the absorption cell to a light output signal; and a differential signal generator which generates a third order differential signal of the light output signal, the method comprising:\n determining, when the predetermined form of the third order differential signal is detected, a return direction of the resonator length based on the waveform; and changing the resonator length to the return direction.
