Details concerning the parameters used to quantify the form and quality of a laser’s spatial beam profile are given in Laser Beam Spatial Profiles. For the beam supply, optics are used to move the beam to the goal position on the pattern with the desired beam shape and focus. However, each optical element between the laser and the goal workpiece will incrementally distort the beam quality. Therefore, both the quantity and quality of every optical element ought to be optimized. For instance, optics with poor floor quality would distort the beam shape, and optical components with an insufficient clear aperture would crop the beam and introduce undesirable diffractive effects.
