Shaped beam是什么
WebbAnother type of laser beam shaping is circularizing a beam, which involves converting an oval or differently shaped profile to a circular one. Laser diodes with no collimating optics will have different divergence angles in the x- and y-axes because of the rectangular shape of the diode’s active region, resulting in oblong beam shapes ( Figure 7 ).
