Beam deflection devices and methods using piezoelectric tube resonance. A beam deflection device may include a laser that produces a beam of light. The beam of light may then be directed through a piezoelectric tube that includes a light guide and one or more piezoelectric elements. The device may also have an optical tip that extends axially from the end of the piezoelectric tube. The piezoelectric tube is coupled with the light source, such that the beam of light is conducted through the light guide and optionally the optical tip. A controller may be communicatively coupled with the light source and the piezoelectric tube. The controller may include instructions to activate the piezoelectric tube at a resonant frequency of the piezoelectric tube, the light guide, and/or the optical tip. The controller may include instructions to activate one or more of the piezoelectric elements at a different power level.
