A method for stabilizing an oscillation frequency separation among a plurality of laser devices wherein a plurality of laser devices are controlled to emit light outputs each having a predetermined frequency so that a frequency separation is stabilized, wherein the plurality of laser devices are divided into a plurality of groups, in each of which the frequency separation is stabilized in accordance with a reference light output of one reference laser device. On the other hand, a plurality of the reference laser devices are controlled to stabilize a frequency separation each other, so that relative frequency separation among the plurality of groups of the plurality of laser devices are stabilized. As a result, a frequency separation of a large number of laser devices is stabilized.
