See also Fig. 1, Fig. 2, Fig. 3 and Fig. 4 earlier, Fig. 1 is quasi-three-dimensional adjusting structure embodiment 1 cross-sectional schematic of the present invention, Fig. 2 is the cutaway view of Fig. 1 three-dimensional adjusting structure A-A, and Fig. 3 is the longitudinal sectional view of elastic hinge seat 1 of the present invention, and Fig. 4 is the transverse sectional view of elastic hinge seat 1 of the present invention.As seen from the figure, quasi-three-dimensional adjusting structure of the present invention, comprise elastic hinge seat 1, a tubulose is regulated overcoat 2 and adjustment screw 3, described elastic hinge seat 1 comprises that the fixed body 105 and less adjustment body 106 and the profile of diameter that connect together are a dome platform shape, the fixed body 105 of this elastic hinge seat 1 is set in described tubulose coaxially and regulates in the overcoat 2, be evenly equipped with a plurality of tapped through holes on the tube wall of described tubulose adjusting overcoat 2 and be embedded and tune for described a plurality of adjustment screw 3, the inner of this adjustment screw 3 is corresponding with the adjustment body 106 of described elastic hinge seat 1.
The fixed body 105 of described elastic hinge seat 1 and the coupling part of adjusting body 106 be provided with two or more not conplane vertical its and the line of crossing axle cut groove 101,103, the end of this groove 101,103 is expanded into circular hole 102,104.
The middle shaft part of described elastic hinge seat 1 is arranged with the light hole road or element to be transferred is embedded seat.
Described tubulose is regulated in the overcoat 2 and is provided with a plurality of elastic hinge seats 1.
The external diameter of described elastic hinge seat 1 and tubulose are regulated overcoat 2 internal diameters and are equated, elastic hinge seat 1 is inserted in tubulose to be regulated in the overcoat 2, and the two forms the cooperation in axle and hole.Uniform three screws on the tube wall of tubulose adjusting overcoat 2 are used for fixing three adjustment screw 3.
Described groove 101,103 and circular hole 102,104 usefulness line cutting modes process, large semicircle tube wall groove 101 and 103 cut direction quadrature, and circular hole 102 and 104 cut direction quadrature make elastic hinge seat 1 have certain elasticity.
The optical element for the treatment of adjusting laser is fixed on the adjustment body 106.
As shown in Figure 5 and Figure 6, elastic hinge seat 1 is inserted in tubulose to be regulated in the overcoat 2, unclamps adjustment screw 3, and elastic hinge seat 1 is regulated overcoat 2 inwalls along tubulose and moved, and can be implemented in the adjusting of the position p1 of optical axis direction to p2.
As shown in Figure 7, three adjustment screw 3 act on the adjustment body 106 of elastic hinge seat 1, make groove 101 to dehisce with circular hole 102 serve as that axle changes, adjust the angle that body 106 produces optical axis thereupon and change, thereby produced perpendicular to optical axis one dimension angle adjustment wherein.In like manner, as shown in Figure 8, three adjustment screw 3 act on the adjustment body 106 of elastic hinge seat 1, make groove 103 dehisce with circular hole 104 serve as the axle change, the angle that adjustment body 106 produces optical axis thereupon changes, thereby has produced perpendicular to another dimension angle adjustment of optical axis.Because groove 101 and 103 cut direction quadrature, circular hole 102 and 104 cut direction quadrature, so the bidimensional of angle adjustment is a quadrature.
Owing in the process of adjusting angle, can't carry out the adjustment of optical axis direction again, so this one dimension adjustment of optical axis direction is accurate one dimension adjustment.
After described three adjustment screw 3 are regulated locking, adjust the position and the angle of body 106 and all determined, need not
Described elastic hinge seat 1 adopts the bronze with certain elasticity and thermal conductivity, perhaps aluminum material, and perhaps No. 65 manganese steel, perhaps the high resiliency steel processes, and does after the processing and show processing accordingly.
Described tubulose is regulated overcoat 2 and is adopted the bronze with certain rigidity and thermal conductivity, and perhaps aluminum material processes.
Further, in tubulose is regulated overcoat 2, add one or more elastic hinge seats, can form two covers or the above adjustment structure of two covers.
Quasi-three-dimensional adjusting structure embodiment 2 of the present invention as shown in Figure 9.Laser crystal 5 is put into crystal cup 6, crystal cup 6 is put into regulated overcoat 2 again.Elastic hinge seat 1 comprises three vertical its large semicircle tube wall grooves, and the end of large semicircle tube wall groove is processed into circular hole, and large semicircle tube wall groove and circular hole process with the line cutting mode, and the cut direction quadrature makes elastic hinge seat 1 have certain elasticity.Treat that light modulation element 4 (outgoing mirror) is fixed on the adjustment body 106 of elastic hinge seat 1, elastic hinge seat 1 is inserted in tubulose to be regulated in the overcoat 2, the inwall that fixed body 105 and tubulose are regulated overcoat 2 cooperates, 501 of laser crystal 5 and 401 of outgoing mirror 4 constitute resonant cavity, regulate the suitable vertically adjusting position of overcoat 2 inwalls at tubulose, can realize adjusting the long effect in chamber.Uniform three screws on the tube wall wall of tubulose adjusting overcoat 2 are used for fixing three adjustment screw 3.Adjustment screw 3 acts on the adjustment body 106 of elastic hinge seat 1, has realized the angular adjustment perpendicular to the both direction of axle.After three adjustment screw 3 were regulated locking, it was just fixing safe to adjust structure.
The quasi-three-dimensional adjusting structure embodiment 3 of minature solide-state laer optical element of the present invention as shown in figure 10, this structure is used for laser diode end-face pump intracavity frequency doubling solid state laser.
Contain two covers in the present embodiment and adjust structure, the second elastic hinge seat 7, adjusting overcoat 2 and three adjustment screw 9 constitute a cover and adjust structures, laser crystal 5 is put on the fixed body of elastic hinge seat 7, treat that light modulation element frequency-doubling crystal 8 puts into the adjustment body of the second elastic hinge seat 7, three adjustment screw 9 are used to regulate the two dimension angular perpendicular to optical axis of frequency-doubling crystal 8, realize the adjustment of the coupling angle of frequency-doubling crystal 8.The first elastic hinge seat 1, adjusting overcoat 2 and three adjustment screw 3 constitute another set of adjustment structures, modulated light is learned the adjustment body that element outgoing mirror 4 is put into the first elastic hinge seat 1, the first elastic hinge seat 1 also is placed into to be regulated in the overcoat 2, slides along regulating overcoat 2 inwalls, and it is long to regulate the chamber; Three adjustment screw 3 are used to regulate the two dimension angular of outgoing mirror 4 perpendicular to optical axis, have realized the adjustment of the two dimension angular in chamber length and chamber.
The second elastic hinge seat 7 comprises the large semicircle tube wall groove 701,703,705 and 707 of four vertical axials in this example, and process circular hole 702,704,706 and 708 at the end of large semicircle tube wall groove 701,703,705 and 707 respectively, as Figure 11 and shown in Figure 12.Elastic hinge seat 7 has bigger adjustment angle than elastic hinge seat 1.
