    • Devices accepted mirror diameters up to approximately 1.3 cm.
    • Resonant frequencies remained above 2 KHz under tested conditions.
    • Mirror translation exceeding +/-20 micrometers was achieved with less than +/-300 V.

    Conclusions:

    • The evaluated piezoelectric devices demonstrate suitability for laser mirror tuning applications.
    • The devices offer a good balance of travel range, resonant frequency, and voltage requirements.
