ABSTRACT:
Driving current in sine wave form is supplied to a semiconductor laser; the laser beam output by this semiconductor laser is caused to split into two laser beams for measurement which mutually interfere after passing through optical paths with different optical lengths. Then, the light intensity of the laser beams for measurement after interference is detected with the means for detecting light; after the high frequency component is extracted from the detection signal of this means for detecting light, bias current applied to the driving current is controlled so that the light intensity of this high frequency component becomes a maximum value.
