A radial power feedback sensor senses the power output of a fiber optic bundle. The fiber optic bundle is arranged generally radially about an axis to carry radiative energy produced by a laser. A spacer is positioned within the fiber optic bundle such that the fiber optic bundle generally surrounds the spacer. The spacer serves to enable the radiative energy to pass therethrough. A photo detector is then disposed adjacent the spacer and is operable to output a signal in response to a measured intensity of the radiative energy passing through the spacer. Accordingly, due to the surrounding of the fiber optic bundle around the photo detector, a greater number of individual photo optic lines are exposed to the photo detector, thereby decreasing the variance between the measure output and the true output of the laser.
