Abstract: Provided is a laser stabilization apparatus including an optical fiber resonator that is in the form of an optical fiber loop with an optical fiber delay-line, and is designed to resonate at a stabilized frequency of a laser, wherein when light emitted from the laser is input to the optical fiber resonator, a transmittance thereof changes according to a frequency of the input light, and a light measurer configured to measure light output from the optical fiber resonator and generate an error signal for stabilizing a frequency of the laser.
