ABSTRACT:
There are disclosed a method and apparatus for stabilizing an oscillation frequency separation among a plurality of laser devices wherein a plurality of laser devices are controlled to radiate output lights each having a predetermined frequency so that a frequency separation is stabilized. Reference pulses are produced in an optical resonator which has periodic resonant frequencies and receives a frequency sweep signal, and beat signals are produced in accordance with the combination of the frequency sweep signal and oscillation frequencies of the plurality of laser devices. The reference signals and beat signals thus produced are processed to produce error signals which are time differences between the producing times of the both signals. The plurality of laser devices are controlled to be driven such that the error signals become a predetermined value.
