[Object] To propose a new and improved control device, a control method, and a program, which are capable of controlling a light path length of a resonator to allow resonance in a mode capable of obtaining a laser light of higher strength. [Solution] Provided is a control device including: a drive section that moves, in an optical axis direction, at least one of a pair of reflecting units in a resonator that includes the at least a pair of reflecting units and a non-linear optical crystal, converts a wavelength of an entering laser light by resonating the laser light and has a plurality of modes that satisfy a resonance condition of the entering laser light; and a control section that controls a light path length of the resonator, by causing the drive section to move the at least one of reflecting units so that the laser light that enters into the resonator changes from a state in which the laser light resonates in a first mode of the plurality of modes to a state in which the laser light resonates in a second mode different from the first mode, on the basis of a detection result of a reflected light from the resonator. |
