An articulated arm for applying a laser beam to a treatment zone has an arm section and a horizontal pivot joint. A spring arrangement acts on the pivot joint and has a cam disk and a pressure member following the cam disk contour as the arm section pivots. The arm section has, relative to a vertical direction, positive and negative pivot angle ranges. In the positive range the spring arrangement relieves the pivot joint from weight forces. When a resting angle in the negative range is reached the articulated arm rests in a support device. A total moment resulting from a weight force moment of the articulated arm and a restoring moment of the spring arrangement acts on the articulated arm about the pivot joint; cam disk contour and spring pretension are matched such that for the resting angle the total moment is oriented toward the support device.
