Abstract: High voltage RTM Piezo Driver has been developed to support special diagnostic applications foreseen for XFEL facility. The RTM is capable of driving 4 piezo actuators with voltages up to ±80 V. The solid-state power amplifiers are driven using 18-bit DACs and sampling rates of 1 MSPS. The bandwidth of the driver is remotely tunable using programmable low pass filters. The 4-channel Piezo Driver unit provides the information of piezo output voltage and current. Three independent test setups have been built to test 4-channel Piezo Driver performance. In the paper we are presenting EOD laser lock to 1.3 GHz FLASH master oscillator using bipolar piezo stretcher (fine tuning). The piezo motor based course tuning has been applied for the long term laser stability measurements. The unipolar piezo actuator operation has been demonstrated for the Origami Onefive laser locked to 1.3 GHz LAB MO. The preliminary results of active stabilization of 3 km fiber link laboratory setup are shown.
