ABSTRACT:
The present invention relates to the selected-wavelength tuning apparatus which is provided with an AOTF, a radio-frequency signal generator, an optical detector, and a controller for detecting lights emitted from the AOTF with the optical detector and for controlling a frequency of the radio-frequency generator so as to detect a light of predetermined wavelength.
