Abstract : We have studied the nonlinear microwave response of expitaxial HTS multilayers and single layers thick films in collaboration with Dr. Dan Oates at MIT Lincoln Lab. In order to make highest quality control we have used multi-YBCO target PLD with in situ high pressure RHEED. The nonlinearity of YBCO thick films improves, as increasing the films thickness, and approaches the lowest values ever reported.
