Embodiment Construction

[0017] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0018] See figure 1 , the laser device 10 provided by the first embodiment of the present invention includes a laser source 11 and an optical module 12 .

[0019] The laser source 11 is used to emit a transverse electromagnetic mode (Transverse Electromagnetic, TEM) TEM xy The laser 101, wherein, x is greater than or equal to 0 and less than or equal to 3, and y is greater than or equal to 0 and less than or equal to 3.

[0020] The optical module 12 is a lenticular lens disposed on the optical path of the laser 101 . The lenticular lens has a first surface 121 adjacent to the laser source 11 , and a second surface 122 opposite to the first surface 121 . The first surface 121 is a cylindrical concave surface, and the second surface 122 is a plane. The laser light 101 emitted by the laser source 11 is transmitted through the first surface 121 of the optica...

Abstract

The invention relates to a laser device comprising a laser source and an optical die set. The laser source is used for emitting laser with a transverse electromagnetic mode TEMxy, wherein x is largerthan or equal to 0 but is smaller than or equal to 3, and y is larger than or equal to 0 but is smaller than or equal to 3. The optical die set comprises a cylindrical lens arranged on a light path ofthe laser, the cylindrical lens is provided with a first surface which is adjacent to the laser source and a second surface which is opposite to the first surface, and at least one of the first surface and the second surface is a cylindrical curved face used for changing the field form of the laser.

Description

technical field [0001] The invention relates to a laser device, in particular to a laser device capable of adjusting the laser field shape. Background technique [0002] With the advancement of semiconductor technology and processing technology, panel cutting technology has developed rapidly. The traditional mechanical cutting technique consists of three steps, namely scribing, splitting and edging. Due to the traditional cutter wheel type scribing, and then using mechanical stress splits, it is easy to cause debris and micro cracks on the cutting surface, resulting in a decline in cutting quality. Therefore, recently, the industry generally adopts laser cutting technology, which has the advantages of better verticality of cutting cracks, smooth cutting surface and higher cutting efficiency. However, in laser cutting technology, the quality of laser cutting depends on the distribution of laser field shape. Therefore, it is necessary to adjust the distribution of the laser...
