The photothermal vibration independently discriminated by the difference between the wavelengths of laser beams is proposed. The micro pattern of optical interference filter was produced, and cantilever beam was independently excited only in the laser beam which penetrated this filter. It was confirmed experimentally that the cantilever beam was vibrated only by the laser beam of the specific wavelength. It is sufficiently possible to control independently by this technique, and it seems to be possible that the optical actuator increases the degree of freedom. In addition, the optical filter was fixed to the cantilever beam itself, and the cantilever beam which was vibrated only by the laser beam of specific wavelength by light absorption was manufactured. The cantilever beam was slightly excited by laser beam of other wavelength. It is necessary to use shape memory alloys or so as the material of the cantilever beam in this case.
