[concrete Implementation Modes]

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

See also Fig. 1 to Fig. 3, synoptic diagram for the utility model laser beam splitter device, the utility model laser beam splitter device 100 can be connected on the laser equipment (figure does not show), accessory device as laser equipment, specifically can be divided into four road laser to the road laser that laser equipment penetrates, and each road laser in time or be to regulate on the energy, and in other embodiments, the laser beam splitter device also is divided into one road laser two-way or more than four road laser.

This laser beam splitter device 100 comprises: a pedestal 10, and this pedestal 10 is roughly rectangular, comprises the base plate 11 that is tabular, is connected a cover plate 12 on this base plate 11 and is installed in a guard shield 13 on this cover plate 12; An incident optical 20 and four output fibers 30, wherein this incident optical 20 is identical with output fiber 30 structures, just incident optical 20 is connected with the laser exit wound of bullet of laser equipment, output fiber 30 is connected on the station, and incident optical 20 and output fiber 30 are connected on the cover plate 12 of pedestal 10 by fiber bench 23 respectively; On beam expanding lens 40, four beam split regulating devices 50 that are positioned at these beam expanding lens 40 the place aheads, and the light path that be positioned at 50 reflector lasers of beam split regulating device successively corresponding with each beam split regulating device 50 four be in the light optical gate 60, four fiber couplers 70 and described four output fibers 30, wherein this beam expanding lens 40, beam split regulating device 50, be in the light optical gate 60 and fiber coupler 70 all are fixed on the base plate 11 of pedestal 10.

Wherein, beam expanding lens 40 is connected with incident optical 20, and the time distortion directional light that will enter beam expanding lens 40 from the laser that incident optical 20 passes through.

Wherein, being centered close on the same straight line of four beam split regulating devices 50, and also being located along the same line with the center of beam expanding lens 40 and the center of incident optical 20 respectively, and beam expanding lens 40 is positioned at the centre of a beam split regulating device 50 and incident optical 20.

As Fig. 4 to Fig. 6, be the structural representation of beam split regulating device, each beam split regulating device 50 comprises: an eyeglass 51, this eyeglass 51 have the first 511 and the second portion 512 of different reflectivity, certainly at other embodiment, this eyeglass can have the different a plurality of parts of reflectivity; The mirror holder device 52 of a fixing len 51; Be fixed on two adjustment parts 53 on this mirror holder device 52; Be located at two clamping pieces 54 of eyeglass 51 both sides and fixing len 51; Be fixed on an adjusting gear 55 on the mirror holder device 52; And be fixed and clamped sheet 54 and the fixture 56 of adjusting gear 55 on mirror holder device 52.The part of described eyeglass 51 is fixed in this adjusting gear 55, and this adjusting gear 55 comprises an adjusting lever 552 and pressed seat 553 of adjusting seat 551 and laying respectively at eyeglass 51 two ends that is positioned at mirror holder device 51 1 sides.
