Embodiment Construction
[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.
[0020] This patent discloses a mechanism for adjusting the divergence and energy of the laser beam, such as figure 1 As shown, it includes: a laser 1, a first deflection mechanism 201, a second deflection mechanism 202, a first fixed mirror group 301, and a second fixed mirror group 302, wherein the laser 1, the first fixed mirror group 301 and The second fixed mirror group 302 is in the laser transmission optical path to realize the first way to change the beam divergence angle of the laser; the first deflection mechanism 201 can cut two mirror groups into the laser transmission optical path to realize the laser transmission The divergence angle of the laser beam can be changed in the second way; the second deflection mechanism 202 can cut the two lens groups into the laser transm...
