Abstract
The utility model provides a large-power fiber laser device with multiple output ends. The large-power fiber laser device comprises a seed source, a power amplifier group, and a fiber splitter. The seed source generates an optical signal with a specific wavelength. The power amplifier group is used for amplifying the output of the seed source. The fiber splitter divides the optical signal emitted by the seed source into multiple channels optical signals. Then multiple channels optical signals are connected with the power amplifier group in order to generate multiple outputs, wherein the output optical power of the multiple outputs can be independently controlled. Compared with a product using a conventional scheme in which light is split at a total output end, the large-power fiber laser device resolves a defect of incapability of independently controlling each output of the product using the conventional scheme, and reduces a requirement for power handling of an optical power amplification stage. Therefore, the reliability of the large-power optical path is increased and cost is reduced.

Background technology
Fiber laser is the most very powerful and exceedingly arrogant research topic, especially high power fiber laser in the current electronic technology research field, has shown in a lot of fields to replace conventional solid laser and CO
2The trend of laser.In the laser marking field, because fiber laser has high beam quality and positioning accuracy, make little nameplate at semiconductor chip and packing, also be usually used in mark on plastic casing, metal.The fiber laser of multiterminal output can offer simultaneously a plurality of labelling head marks, thereby raise the efficiency and Cost reduction.Method commonly used is the output of laser to be realized the output of multichannel with the fiber splitter light splitting at present.As shown in Figure 1, existing high power fiber laser when offering a plurality of labelling heads and carry out mark, the output T that its mark light path is last
oNeed the larger power of output.
But there is following defective in above-mentioned existing multichannel output high power laser: because the light signal peak power of output is higher before the light splitting, therefore cause easily the damaging thresholding above the optical fiber in the light path or optical device; And use high power device in light path, its cost also increases thereupon; Simultaneously high-power in order to bear, as need in light path, to use large core fiber, thus cause beam quality to worsen; And because the output T of laser light path
oTherefore the light splitting of output free space can't independently control each road output T
1, T
2Luminous power, cause a plurality of labelling heads can only synchronously beat same content; And because each device in the above-mentioned laser light path moves in powerful light path, its reliability reduces.
Summary of the invention
For addressing the above problem, the high power fiber laser that the multiterminal that the utility model provides a kind of every road output independently to control are exported reduces cost and the reliability that improves system simultaneously.
The utility model provides a kind of high power fiber laser of multiterminal output, comprise: one produces the seed source of the light signal of specific wavelength, one is used for amplifying the power amplifier group of the output of seed source, with an optical fiber splitter, it is characterized in that: above-mentioned optical fiber splitter is independently connected to above-mentioned power amplifier group after the above-mentioned light signal that is sent by seed source is divided into multi-path light.
Wherein, preferred version is: above-mentioned power amplifier group is set to multi-stage fiber amplifier, and independently luminous power control is carried out in each road output.
Wherein, preferred version is: between above-mentioned seed source and the above-mentioned fiber splitter a pair of light signal is set
The power amplifier that amplifies in advance.
Wherein, preferred version is: between above-mentioned fiber splitter and the above-mentioned power amplifier group power amplifier that a pair of light signal amplifies in advance is set.
The utility model has the advantage of: at first, owing in light path, optical fiber splitter is set so that the every road output of light signal can independently be controlled, therefore can the different content of mark; Secondly, therefore each road power amplifier power output less adopts lower-cost low-power device and gain fibre; Wherein, gain fibre can adopt the optical fiber of less core diameter, thereby has improved beam quality; At last, the maximum power ratio prior art of exporting in the whole light path little improved the reliability of whole light path system.
