Abstract
The invention provides an apparatus and a method for adjusting laser beams of a CO2 laser device, and the apparatus comprises a CO2 laser device, a first reflecting lens, a second reflecting lens, a third reflecting lens, a polarization apparatus, and a polarizing beam combiner. A laser beam emitted from the CO2 laser device enters and passes the first reflecting lens, and the incident laser is separated into two beams by the first reflecting lens, a first laser beam and a second laser beam, respectively. The first laser beam goes on traveling along a same path, and directly enters the polarizing incident beam combiner. The second laser beam is reflected and enters the second reflecting lens, and under a guidance of the second reflecting lens, the laser beam passes the polarization apparatus, selecting a polarizing direction of 90 degrees, and then under the guidance of the third reflecting lens, the polarized laser beam enters into the polarizing beam combiner. The polarizing beam combiner combines the first laser beam and the second laser beam into a laser beam. Through the method, the laser beam emitted from the CO2 laser device can change from an oval laser spot to a non-oval laser spot, so that ovality of the laser is improved, and a spot size is reduced to achieve the objective of improving laser beam quality.
Description
[technical field]
The present invention relates to a kind of light beam adjusting gear and method thereof of CO2 laser instrument.
[background technology]
The CO2 laser instrument is owing to himself characteristic, and its light beam presents oval hot spot many times, when being used for the machine work of CO2 laser marking, tend to make that line thickness is inconsistent like this; The beam quality that need get well during Laser Processing in addition could reach better machining effect with the point of laser focusing Cheng Gengxiao.
[summary of the invention]
The present invention provides a kind of light beam adjusting gear and method thereof of CO2 laser instrument, can CO2 laser instrument script ovalize hot spot be become non-oval hot spot, improve the laser ovality thereby reach, and the squeezed light spot size improves the purpose of beam quality.
The present invention provides a kind of light beam adjusting gear of CO2 laser instrument; Comprise: a CO2 laser instrument, at first reflecting optics of 1 on the light path, one second reflecting optics, one the 3rd reflecting optics, a polarization apparatus and a polarization light combination mirror sheet between second reflecting optics and the 3rd reflecting optics; This polarization light combination mirror sheet has the bundle plated film face that closes; Wherein, The reflecting surface of the reflecting surface of the reflecting surface of second reflecting optics and first reflecting optics and second reflecting optics is parallel relation; The reflecting surface of the reflecting surface of the 3rd reflecting optics and second reflecting optics is vertical relation, and the bundle plated film face that closes of the reflecting surface of the 3rd reflecting optics and polarization light combination mirror sheet is parallel relation.
The present invention also provides a kind of light beam method of adjustment of CO2 laser instrument, and it comprises the steps:
A, CO2 laser instrument output laser;
The laser incident of b, the output of CO2 laser instrument is through first reflecting optics, and first reflecting optics is divided into two bundle laser with incident laser;
C, via the two bundle laser that first reflecting optics is divided into, be respectively the first bundle laser and the second bundle laser, the first bundle laser continues along former road to propagate, and directly gets into incident polarization light combination mirror sheet; The second bundle laser-bounce gets into second reflecting optics;
D, the second bundle laser are selected 90 ° through polarization apparatus rear polarizer direction under the guiding of second reflecting optics, through the guiding of the 3rd reflecting optics, incide in the polarization light combination mirror sheet again;
E, polarization light combination mirror sheet are with the first bundle laser and the synthetic beam of laser of the second bundle laser.
The laser beam that the CO2 laser instrument sends through method of the present invention, can become non-oval hot spot with CO2 laser instrument script ovalize hot spot, improve the laser ovality thereby reach, and the squeezed light spot size improves the purpose of beam quality.
[description of drawings]
Combine embodiment that the utility model is done further to describe with reference to the accompanying drawings.
Fig. 1 is the synoptic diagram of the light beam adjustment of CO2 laser instrument of the present invention;
Fig. 2 is another synoptic diagram of the light beam adjustment of CO2 laser instrument of the present invention.
[embodiment]
Below in conjunction with description of drawings and embodiment the present invention is further specified.
Of Fig. 1 is CO2 laser beam synoptic diagram of the present invention; It comprises: the CO2 laser instrument 10 of input laser beam 100, at first, second, third reflecting optics 20,30,40 on the beam path, at the second and the 3rd reflecting optics 30, a polarization apparatus 50 and a polarization light combination mirror sheet 60 between 40, polarization light combination mirror sheet 60 has the bundle plated film face that closes that penetrates laser.
