Background technology
Be accompanied by the fast development of full science and technology, semiconductor laser technique is constantly ripe, thereby promotes the extensive use of high power semiconductor lasers in the whole world.Compare semiconductor laser with gas laser and have many good qualities, photoelectric conversion efficiency height, volume are little, in light weight, cooling require relatively low etc., but semiconductor laser also comes with some shortcomings, the single channel power output is lower, collimation is relatively poor relatively etc.At two shortcomings more than the semiconductor laser, solution is: multimode output solves the little problem of power; The method that adds collimating lens solves the problem of collimation difference.Owing to be that multimode output just must come output beam is collimated with a plurality of collimating lenses, the arrangement of a plurality of camera lenses has so just appearred.Shape etc. illuminated in actual applications or that be heated the zone is different, add top grade as linear heating, annular heating, circle, present solution all is the set of lenses that different operational environments is changed different modes of arranging, and has also increased the cost of equipment when having reduced operating efficiency.
Summary of the invention
The objective of the invention is to propose a kind of set of lenses and arrange adjustable multi-channel output semiconductor laser, produce laser by high power semiconductor lasers, by flexible optical fibre laser is transported to set of lenses, with different spread geometries laser is exported as requested, object is shone or heats, with energy savings.
The set of lenses that the present invention proposes is arranged adjustable multi-channel output semiconductor laser, comprises lasing light emitter and set of lenses, and set of lenses links to each other with lasing light emitter by optical cable; Described set of lenses is made up of many lens, many lens are installed in respectively on the corresponding mounting rod, be respectively equipped with motor, driving gear and driven gear on the every mounting rod, the mounting rod of the mounting rod of any last lens in many lens and adjacent back lens links mutually by a drive link, the mounting rod of last lens and the front end of drive link are meshing with each other, the mounting rod relative fixed of the rear end of drive link and back lens; With the front end and the driven gear relative fixed of the intermeshing drive link of mounting rod, driven gear is by driving gear and motor linkage.
The set of lenses that the present invention proposes is arranged adjustable multi-channel output semiconductor laser, and its advantage is: can more effective performance efficiency of laser, reduce energy dissipation.More reasonably control optical power density.A kind of set of lenses that the present invention proposes is arranged adjustable multi-channel output semiconductor laser, especially can be used for the laser deicing system,, change the spread geometry of camera lens arbitrarily according to the shape of deicing object, in the ice detachment laser use more flexible, thereby improve deicing efficiency greatly.

Among Fig. 1-Fig. 2, the 1st, lasing light emitter, the 2nd, optical cable, the 3rd, set of lenses, the 4th, laser beam output, 5 is first lens, and 6 is second lens, and 7 is n lens, the 8th, drive link, the 9th, driven gear, the 10th, driving gear, the 11st, lens mounting rod, the 12nd, motor.
Embodiment
The set of lenses that the present invention proposes is arranged adjustable multi-channel output semiconductor laser, and its structure comprises lasing light emitter 1 and set of lenses 3 as shown in Figure 1, and set of lenses 3 links to each other with lasing light emitter 1 by optical cable 2.The structure of set of lenses 3 as shown in Figure 2, set of lenses is made up of many lens, comprises first lens 5, second lens 6, until n lens 7, many lens are installed in respectively on the corresponding mounting rod 11, are respectively equipped with motor 12, driving gear 10 and driven gear 9 on the every mounting rod.Any last lens in many lens, link mutually by a drive link 8 as the mounting rod 11 of first lens 5 among Fig. 2 mounting rod with adjacent back lens, the mounting rod 11 of last lens is meshing with each other the mounting rod relative fixed of the rear end of drive link 8 and back lens (being second lens 6 among Fig. 2) with the front end of drive link 8.With the front end and driven gear 9 relative fixed of the intermeshing drive link 8 of mounting rod, driven gear 9 is by driving gear 10 and motor 12 interlocks.
Set of lenses of the present invention is arranged in the adjustable multi-channel output semiconductor laser, and optical cable 2 links to each other with the afterbody of mounting rod 11, and motor 12 is fixed on the mounting rod 11.The arrangement of set of lenses motor 12, driving gear 10, driven gear 9, mounting rod 11 and drive link 8 mutual interlocks successively realizes.The input of motor 12 links to each other with laser 1 by optical cable 2, and the output of motor 12 links to each other driving gear 10 and driven gear 9 composition drive systems with driving gear 10 on the lens mounting rod.When driving driven gear 9 rotations when motor 12 driving driving gears, 10 rotations, because the front end and driven gear 9 relative fixed of drive link 8, the other end of the rotation drive drive link of driven gear 9 centers on mounting rod 11 and rotates.Because mounting rod 11 and second lens 6 are relatively-stationary, so the rotation of mounting rod 11 just can drive second lens 6 adjacent with first lens 5 and also centers on mounting rod 11 rotations.By that analogy, back one lens can rotate around last lens according to need of work arbitrarily, thereby the difference that realizes many lens is arranged.
The adjustment process of spread geometry as shown in Figure 2, micromachine 12 drives driving gear 10 and rotates, driving gear 10 drives driven gear 9 and rotates, driven gear 9 drives drive link 8 and rotates, drive link 8 drives second lens 6 and rotates around mounting rod 11, thereby has realized the change of first lens 5 and 6 relative positions of second lens.Can realize the change of position by the rotation of controlling corresponding micromachine between any two adjacent lenses.Finally can make set of lenses form linear array as shown in Figure 3, rectangular arranged shown in Figure 4, circular arrangement shown in Figure 5, or the like.
But described micromachine adopts the fine setting motor of self-locking, can adopt battery-powered or laser energy supply.The rotation of motor is to control by the controller that is positioned at laser, and each motor has independently control signal.Can set the rotational angle of different motors at the controller end, thereby realize that the position can independently be regulated between any two lens mounts, so just guarantee the flexible transformation of set of lenses spread geometry.
Described driving gear 10 is formed drive system with driven gear 9, and driving gear 10 drives drive link 8 rotations by driven gear 9, thereby realizes changing the change of relative position between adjacent two lens, the final purpose that realizes the arrangement of change set of lenses.
In one embodiment of the present of invention, the motor model of using is Shenzhen 20GP130-107 of Wanda's motor Manufacturing Co., Ltd type reducing motor, power output 0.72W.The focal length of lens is 40cm, the non-spherical lens of plating 980nm laser anti-reflection film, and printing opacity power is 70W.
