Abstract
The utility model discloses a solution preparation unit of solid containing dregs, and is particularly suitable for the solution preparation of calces. Besides a solution tank and a mechanical stirring device, the utility model is also provided with a taking and sorting device which is composed of a short pipe for solution outlet, a soft pipe, and a floater. The utility model can always takes the upper clear solution under a surface solution and can prevent slag substance from admixing; Thus, compared with the existing solution, the solution with higher technical quality and larger activity can be achieved, auxiliary apparatus and air supply condition are eliminated, and stain is avoided.
Description
The utility model relates to a kind of semiconductor laser emitting head, particularly a kind of red light semiconductor laser beam emitting head that has the two-sided lens fiber coupler.
Semiconductor laser is with its small size, high power density, long service live, low-power consumption, direct distinguishing feature such as High Speed Modulation and be widely used in key areas such as photo-electric control, laser printing, optical disc storage.Aspect the red light semiconductor laser beam emitting head, all adopt optical lens group directly to collimate semiconductor laser beam at present.Though this method can solve the rounding problem of semiconductor laser ellipse light spot, process conditions require high, and light path control is dumb, and the optical output power dynamic range is little.Therefore, flying print, the CD of present red light semiconductor laser beam emitting head write, laser medicine is severely limited in using.
The purpose of this utility model is that a kind of novel red light semiconductor laser beam emitting head will be provided, and it can be avoided the shortcoming of above-mentioned emitting head and improve the quality of laser beam effectively.
The purpose of this utility model can reach by following measure: the elliptical beam of semiconductor laser output is collimated with unzoned lens, advance the multimode silica fiber by another Lens Coupling, the light that optical fiber connector is exported is through collimated or focusing again.At this moment hot spot is roundingization, and light path can be crooked arbitrarily with multimode fiber.If adopt the multi-channel optical fibre coupler, just can realize multi-path laser unification road output or the output of one road laser branch multichannel, thereby increase the dynamic range of luminous power output.
The utility model is because only need just can realize the light beam roundingization with common multimode fiber, so structure is simple especially; Simultaneously owing to given full play to the soft and random characteristic of bending of optical fiber, so widened the existing scope of application; In addition owing to the fiber coupler by interchangeability can synthesize or decompose laser output power easily, so can obtain bigger laser output power dynamic range, be particularly suitable for using the light source of complete machine as high speed laser printer, CD drive, laser therapeutic apparantus etc.
The concrete structure of utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 (a) is according to the single channel laser beam emitting head structure chart that the utility model proposes.
The drawing of Fig. 1 (a) is described as follows: (1) is red light semiconductor laser; (2) be simple collimating lens, it carries out general collimation to the output divergent beams of semiconductor laser; (3) be general semiconductor laser emitting head; (4) be one and exchange interface, can connect the laser of different size according to different needs; (5) be condenser lens, it advances optical fiber with the light beam coupling that receives; (6) be general multimode silica fiber, softness can be crooked arbitrarily; (7) be the bright dipping collimating lens, it will be the divergent beams of roundingization collimate again; (8) be a typical prior art product---two-sided lens multi-module optical fiber coupler, form by collector lens, optical fiber and collimation output lens; (9) be one and exchange interface, can connect collector lens, another fiber coupler or other optical element as required; (10) be an optical element.
The red light semiconductor laser beam is the ellipse divergent beams, after the planoconvex spotlight conversion, can regard as and be subparallel elliptical beam, focusing on core diameter through planoconvex spotlight again is 50 μ m---in the quartzy optical cable of single core multimode of 100 μ m, the round divergent beams of the terminal output of optical cable, after the planoconvex spotlight conversion, be connected with a focus lens group again, thereby obtain the very high laser beam of optical quality.
Fig. 1 (b) is the embodiments of three sublasers with synthetic one road laser output of the two-sided lens fiber coupler of a prior art products 3 * 1, the independent respectively control of three road laser.
To be a sublaser be divided into the embodiment of three road laser output with the two-sided lens fiber coupler of a prior art products 1 * 3 to Fig. 1 (c), and the output of three road laser can connect corresponding component as required respectively.Connect if these embodiment are carried out reasonable combination, just can constitute red light semiconductor Laser emission net.
