Abstract
The utility model discloses a fiber laser focalizer, of which the integral structure is a metal pipe. The fiber laser focalizer comprises two parts, namely a focalizing system and a pneumatic device capable of automatically going up and down; the two parts are tightly connected through a connecting rod (9) and are simultaneously fixed on a cutter holder; a laser beam can be focused into a light spot smaller than 0.3 mm by the focusing system; the focusing system comprises a focusing barrel (3) and a focusing lens (4), is coupled with an energy transmission fiber (1) and ensures that the emitting direction of laser is consistent with the optical axis of the focalizer; and a vent pipe (11) is arranged in a position near a laser cutter bit and adopts an air pump or a high-pressure nitrogen gas pump to blow in air or nitrogen gas through a vent nozzle (5). Through the adoption of the fiber laser focalizer, not only the purpose of diminishing the light spot is achieved, but also a set of integral device for cutting, ablating and the like is formed.
Description
Technical field
The utility model belongs to optical technical field, is specifically related to a kind of optical-fiber laser focalizer.
Background technology
The light of Laser output passes through Optical Fiber Transmission usually, after laser passes through Optical Fiber Transmission, the spot size of institute's outgoing determined by the aperture of optical fiber, in actual the use, in order to adapt to the needs of less thinner hot spot, be necessary to add a focusing system at the end of optical fiber output light, to reach the purpose of dwindling hot spot, especially when being used for the purposes such as laser cutting, laser ablation, but due to can not with cutting or the combination of ablation device, just making often needs re-adjustments, brings a lot of inconvenience.
The utility model content
The utility model provides a kind of optical-fiber laser focalizer for problems of the prior art, has both reached the purpose of dwindling hot spot, forms again the whole device that is used for the purposes such as cutting, ablation of a cover.
the technical solution of the utility model is: a kind of optical-fiber laser focalizer, its overall structure is metal tube, but pneumatic means two parts that comprise focusing system and automatic lifting, two parts closely connect, but the pneumatic means of focusing system and automatic lifting is fixed on the base of tool simultaneously, be fixedly connected with by fixed screw 10 with the base of tool, and connect by connecting rod 9, laser beam can be focused into hot spot less than 0.3mm by focusing system, described focusing system comprises focusing barrel 3 and condenser lens 4, itself and energy-transmission optic fibre 1 are coupled, and the direction of assurance laser ejaculation and the optical axis coincidence of described focalizer, breather pipe 11 is set near laser probe, described breather pipe 11 adopts air pump or chews 5 with the elevated pressure nitrogen air pump by ventilation and is blown into air or nitrogen,
Described energy-transmission optic fibre 1 is fixed by lock screw 2;
Described pneumatic means comprises cylinder 6.
By referring to the accompanying drawing description of a preferred embodiment, above-mentioned and other objects, features and advantages of the present utility model will be more obvious.
