We have fabricated and tested several 8.8‐GHz coplanar waveguide resonators made from laser ablated YBa 2 Cu 3 O 7‐b thin films on LaAlO 3 substrates. A quality factor of 1250 at 77 K was measured. A correlation between the microwave performance of the resonators and the critical temperature and morphology of the films was observed.
