An injection-locked laser is disclosed. The injection-locked laser comprises a seed laser, an oscillator into which a certain component of light output from the seed laser is injected as seed laser light, a frequency converter which shifts a frequency of the remaining component of the light output from the seed laser, a photodetector which detects light obtained by synthesizing the light output from the oscillator and the light output from the frequency converter, and a controller which controls an optical path length of the oscillator based on a beat signal component contained in the signal output from the photodetector.
