Embodiment 3
[0117] Embodiment 3, two drilling laser beam combined drilling system. Combine below image 3 The system provided in this embodiment will be described.
[0118] This embodiment is a variant of Embodiment 1. The laser group 1 retains the S polarization end laser group 12. Correspondingly, the laser beam expander group 2 retains the S polarization end laser beam expander group 22, and the laser beam rotation modulator group 3 The laser beam rotation modulation group 32 at the S polarization end is retained, the laser beam combiner 4 retains the S polarization end laser beam combiner 42 , and a third reflective beam combiner 426 is added. The heating and cleaning laser 201 outputs the heating and cleaning laser beam 200, which is reflected and combined by the third reflective beam combining mirror 426, and outputs the heating and cleaning laser beam 202 whose optical axis is parallel to the rotational symmetry axis of the drilling laser beam. The beam 202 has a beam diameter of...
Embodiment 4
[0123] Embodiment 4. A drilling system with dual hollow motorized spindles in parallel and rotating laser beams combined with two beams. Combine below Figure 4 and Figure 8 The system provided in this embodiment will be described.
[0124] This embodiment is still a variant of Embodiment 1. Such as Figure 4 As shown, the laser group 1 in this embodiment includes a P-polarized end laser group 11 and an S-polarized end laser group 12, the 11 includes a first drilling laser 111, and outputs a first drilling laser beam 113; the S-polarized The end laser group 12 includes a fourth drilling laser 122 outputting a fourth drilling laser beam 124 .
[0125] The laser beam expander group 2 includes a P polarization end beam expander group 21 and an S polarization end beam expander group 22, and the P polarization end beam expander group 21 includes a first laser beam expander 211, and the first The drilling laser beam 113 is expanded by the first laser beam expander 211 to outpu...
Embodiment 5
[0134] Embodiment 5. A hollow electric spindle and a swing angle compression galvanometer are connected in parallel to rotate a laser double-beam combining drilling system. Combine below Figure 5 and Figure 8 The system provided in this embodiment will be described.
[0135] This embodiment has carried out some improvements on the basis of the foregoing embodiment 4, mainly adding a heating and cleaning laser 201 on the basis of the foregoing embodiment 4, and reducing the laser refraction scanning module 5, and setting of the heating and cleaning laser 201 Before the laser beam combiner 4, the heating and cleaning laser 201 emits a heating and cleaning laser beam 200, the heating and cleaning laser beam 200 is split by the first laser beam combining element 413, and 50% reflected into the laser collector at the P polarization end 414, 50% of the transmission becomes a part of the P-polarized laser combined incident beam 415; the P-polarized laser combined incident beam 41...
