Embodiment
The invention will be further described with reference to the accompanying drawings and examples.
A kind of multikilowatt optical fiber high power thermal controls apparatus using full liquid medium of the invention, including cooling material entrance and cold
But material exports, fiber entrance and fiber outlet etc..As illustrated in fig. 1 and 2, a kind of multikilowatt optical fiber Gao Gong using full liquid medium
Rate thermal controls apparatus, Yb dosed optical fiber 18 enters system from fiber entrance 1, into pipeline 2, then by adapter 3, pipeline 4, T
Word interface 5, pipeline 6, adapter 7, into long soft-pipe road 8, then by adapter 9, pipeline 10, T words interface 11, pipeline 12, turn
Joint 13, pipeline 14, go out system from fiber outlet 15.
Cooling material in cooling material machine accesses T words interface 5 by cooling material entrance 16 and enters system, then exports 17 by cooling material
System is picked out from T words interface 11.
Fiber entrance 1 and fiber outlet 15 ensure to seal respectively.
Cooling material is flowable liquid medium.
In said apparatus, cooling material passage parcel optical fiber, the mode to be radiated indirectly with tradition have significant structure distinguish and
Effect is distinguished.Caused heat on optical fiber is directly taken away in cooling material flowing.
Further, cooling material entrance 16 and cooling the material outlet 17 is respectively arranged on gain fibre both ends, and fusion point can be put
Enter in passage.
In order that the flow velocity of cooling material in the channel is as far as possible uniform, the sectional area of the cooling material entrance is cut slightly larger than passage
Area.
The length of soft pipeline 8 is gain fibre length needed for system, generally higher than 10m, and softness can be needed by system
Coiled.
Detailed data in conjunction with the embodiments is described further.
