1. Apparatus, comprising:
a catheter comprising an elongated member having a member distal end and an axis of symmetry, the member distal end being configured to be inserted into an orifice of a body of a living subject;
a magnetic sensor located in the member distal end;
cup-shaped electrode fixedly attached to and capping a termination of the member distal end, the electrode being configured to convey radiofrequency (RF) energy to tissue of the body in contact with the electrode so as to ablate the tissue, wherein the cup-shaped electrode includes a base portion and a cylindrical wall portion surrounding the base portion;
a fiber optic (FO) extended along the axis of symmetry so that a FO distal end penetrates the electrode through the base portion, the FO having an FO proximal end;
a laser coupled to the FO proximal end and being configured to input optical energy to the tissue, via the fiber optic, so as to ablate the tissue; and
a processor coupled to actuate the laser and to supply RF energy to the electrode.
