Abstract
A laser comprises at least two-channel laser generating mechanisms and a light path selective reflection output mechanism, wherein the light generated by the two-channel laser generating mechanisms is combined into one-way output laser via the light path selective reflection output mechanism; the light generated by the two-channel laser generating mechanisms enters the light path selective reflection output mechanism through axially symmetrical distribution along the central axis; the light path selective reflection output mechanism comprises reflecting mirrors and a light path selective drive unit used for controlling the reflecting mirrors to act and carrying out time-sharing selection on each incident light; and the incident light is reflected out of the light path selective reflection output mechanism by the reflecting mirrors along the central axis in a manner of time-sharing selection. By adopting multi-channel laser for light exit through time-sharing, the working frequency of the laser can be effectively improved.

Compared with prior art, laser of the present invention, the rotation that drives speculum by the rotation of adopting motor realizes multi-path laser timesharing bright dipping, can improve the laser works frequency effectively.
Description of drawings
Fig. 1 is the light schematic diagram of laser embodiment of the present invention, wherein shows the light path of the laser that one road laser generating mechanism produced.
Fig. 2 is the light schematic diagram of laser embodiment of the present invention, wherein shows the light path of the laser that another road laser generating mechanism produced.
Embodiment
Be described in further detail below in conjunction with the most preferred embodiment shown in the accompanying drawing.
As depicted in figs. 1 and 2, laser embodiment of the present invention comprises two-way laser generating mechanism 1 and a light path selection reflection output mechanism 2, and the bright dipping that two-way laser generating mechanism 1 is produced selects reflection output mechanism 2 to synthesize one tunnel output laser via light path.Among the figure, the direction of arrow is the direction signal of laser transmission, and wherein, Fig. 1 shows a light path, and Fig. 2 shows another light path.
The bright dipping that two-way laser generating mechanism 1 is produced is incident to the symmetrical distribution of 4 property light path and selects reflection output mechanism 2 along the axis.
Two-way laser generating mechanism 1 comprises two laser generating mechanisms 1 that structure is identical, and these laser generating mechanisms 1 are the symmetrical distribution of 4 property along the axis, that is to say, the optical component in the two-way output mechanism 1 is to be the circumferential distribution at center with axis 4.Optical component in the laser generating mechanism 1 comprises first speculum 11, laser cavity 12, first outgoing mirror 13, second speculum 14 and the 3rd speculum 15, the laser that laser cavity 12 produces transfers to the 3rd speculum 15 and outgoing via first outgoing mirror 13 and second speculum 14.
Two-way laser generating mechanism 1 can be simultaneously in running order, just produces bright dipping simultaneously, thus two-way incident light synthetic a branch of output laser; Also can be to divide into the in running order and one tunnel 1 liang of class of laser generating mechanism that is in backup status of one road laser generating mechanism 1, in running order road laser generating mechanism 1 produces bright dipping when flat, 1 of the road laser generating mechanism that is in backup status only can not normally produce bright dipping at a road in running order laser generating mechanism 1, such as: when damage or power descend, just produce bright dipping, thereby can improve the useful life of whole laser.
Light path selects reflection output mechanism 2 to comprise speculum 21 and in order to 21 actions of control speculum and each road incident light is carried out the light path that timesharing chooses select driver element 22, and each road incident light is 4 to reflect light path and select reflection output mechanism 2 along the axis in the selected mode of timesharing via speculum 21.
Light path selects driver element 22 to comprise in order to the mount pad 221 that holds speculum 21, in order to the motor 222 of drive installation seat 221 actions and in order to the checkout gear 2223 of the initial position of detecting motor 222.2221 of motor 222 is fixedlyed connected with mount pad 221, and the axle 2221 of motor 222 is positioned on the axis 4, thereby the rotation of the axle 2221 of motor 222 can drive the rotation of speculum 21, and the bright dipping of one road laser generating mechanism 1 can be alternately chosen in the rotation of speculum 21, make its reflection through speculum 21, and 4 ejaculations along the axis.Need to prove that said choosing is meant when speculum 21 is in suitable position here, can just one road incident light be reflexed on the axis 4 that at this moment another not selected incident light then can not be reflected onto on the axis 4.
Laser embodiment of the present invention also can comprise in order to the output coupling mechanism 3 to travel direction adjusting of output laser and shaping.Output coupling mechanism 3 comprises first speculum 31, second speculum 32 and coupler 33, first speculum 31 is positioned on the axis 4, this structure can make things convenient for the laser output of laser and use, such as: can by the optical fiber that is coupled to coupler 33 laser be derived easily.
Need to prove that each speculum described in the laser embodiment of the present invention preferably, is total reflective mirror.
More than, only be the present invention's preferred embodiment, be intended to further specify the present invention, but not it is limited.All simple substitution of carrying out according to above-mentioned literal and the disclosed content of accompanying drawing; such as: above-mentioned two-way laser generating mechanism is changed to three the tunnel, the four tunnel and even multichannel more; again such as the structural design that above-mentioned output coupling mechanism is changed to other, all at the row of the scope of the present invention.
