Abstract
We present a piezo-driven translatable mirror with excellent pointing stability, capable of driving at frequencies up to tens of kilohertz. Our system uses a tripod of piezo actuators with independently controllable drive voltages, where the ratios of the individual drive voltages are tuned to minimize residual tilting. Attached to a standard {\varnothing}= 12.7mm mirror, the system has a resonance-free mechanical bandwidth up to 51kHz, with displacements up to 2μm at 8kHz. The maximum static steering error is 5.5rad per micrometer displaced and the dynamic steering error is lower than 0.6rad/μm. This simple design should be useful for a large set of optical applications where tilt-free displacements are required, and we demonstrate its application in an ensemble of cold atoms trapped in periodically driven optical lattices.
