Precision adjustment has many applications in various fields, particularly in laser generation systems and precision engineering. In this paper, a laser forming method for the precise adjustment of a rod with a diameter of several millimeters is investigated. Experiments on precision laser adjustment are carried out using a fiber-coupled passively cooled CW diode laser. The effect of important parameters is investigated in detail. Parametric studies are carried out to determine suitable processing windows at which a small and stable laser-adjusting angle is obtained. A coupled thermomechanical model established using the finite element method is validated and applied to predict the deformation of the rod and better understand the mechanism of precision laser adjustment. A simple closed-form expression for the precision laser-adjusting angle is proposed. An application on precision laser adjustment is presented.
