Experiments. a Radial (r) and axial (z) particle position, and corresponding laser power (P) for a 4.9-μm-diameter polystyrene held in the intracavity optical trap. b Dependence of the laser power on the radial and axial position of the particle. The positions indicated with i, ii, iii, and iv correspond to particle position and laser power configurations similar to those illustrated in the diagrams shown in Fig. 3a. The points (i)–(iv) correspond to the configurations shown in Fig. 3a, and the dashed lines correspond to the insets graphs the dependence on z and r on the left and bottom, respectively
