Abstract
A round metal chamber current turning laser device comprises a box body, a fan, a heat exchanger, a round chamber, electrodes, operation gaseous current, a reflector, and an output mirror, and is characterized in that the laser is provided with a circular light chamber, the chamber wall is made of metal, the whole circular chamber is divided into a plurality of sections, the center lines of the input current channel and the output current channel of every chamber section are on the same plane, the center line of the output current channel deflects from the center line of the input current channel to a certain angle, and the input current channel of every section is uniformly distributed on the circle of the circular chamber with the same revolving direction. The utility model has the advantages of a simple structure, small volume, low cost, and the availability of laser bean of high quality with hectowatt or myriawatt.
Description
Technical field
The utility model belongs to gas stream ejector half laser.
Background technology
High power gas stream ejector half carbon dioxide laser commonly used both at home and abroad has two kinds, and the one, cross-flow laser, the 2nd, axial flow laser.I, the circular metal cavity gas laser of invention obtained patent for invention (98113603.6) last time, and its principal character is that intracavity gas flows and is three-dimensional spiral shape to be called for short eddy flow (Helical flow) laser.But, intracavity gas is three-dimensional spiral shape, the structure more complicated of laser because flowing.
Summary of the invention
The purpose of this utility model is to provide a kind of circular metal cavity turn of tidal stream laser, its principal character is that intracavity gas flows and to rotate for two dimension, be called for short turn of tidal stream (Rotation flow) laser, it is simple in structure, volume is little, cost is low, can obtain the high-quality laser beam from hectowatt grade to the myriawatt level.
Circular metal cavity turn of tidal stream laser of the present utility model, it has casing, blower fan, heat exchanger, cylindrical cavity, electrode, working air current, speculum, outgoing mirror, the whole cylindrical cavity that it is characterized in that laser is divided into plurality of sections, and the entrance channel of each section of cylindrical cavity and the center line of outlet flow are positioned at same plane; The outlet flow center line is with respect to angle of entrance channel center line deflection; The entrance channel of each section is uniform on the circumference of cylindrical cavity, and rotation direction is identical.
As above-mentioned laser, it is characterized in that the diameter of the width of runner less than cylindrical cavity.
As above-mentioned laser, it is characterized in that the entrance channel center line of cylindrical cavity does not intersect with the chamber axle.
As above-mentioned laser, an electrode that it is characterized in that laser is made up of a plurality of mutually insulateds and electrode unit with air cooling runner.Another electrode is an overall structure, has the water-cooled runner.
Circular metal cavity turn of tidal stream laser of the present utility model has following two big characteristics:
1, can obtain simple in structurely, volume is little, the laser that cost is low
The one, working air current belongs to the two dimension rotation, thereby laser is simple in structure, is convenient to processing and manufacturing; The 2nd, because unlike the axial flow laser, adopt high roots blower of price or turbofan, but adopt low centrifugal blower or the flow-mixing blower fan of price.The 3rd, because of the utilance of active population in the chamber, single pass turn of tidal stream laser is far above single pass cross-flow laser.
2, can obtain the high laser beam of beam quality
Laser of the present utility model, the mutual dislocation of turn of tidal stream and each cylindrical cavity section makes the projecting gain of the gain at center in the chamber, and makes the circumference gain profiles even, thereby can obtain the uniform high-quality laser beam of power circle distribution in the employing chamber.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.Wherein, 1 casing, 2 blower fans, 3 heat exchangers, 4 entrance channels, 5 outlet flow, 6 electrodes, 7 electrodes, 8 cylindrical cavities, 9 chamber axles, 10 electrode water-cooled runners, 11 electrode air cooling runners, 12 working air currents.All arrows are represented airflow direction.
Fig. 2 is the cylindrical cavity segmental structure schematic diagram of the utility model embodiment.Wherein, 13 speculums, 14 outgoing mirrors.
Embodiment
The circular metal cavity turn of tidal stream laser of the utility model embodiment, it has casing 1, blower fan 2, heat exchanger 3, cylindrical cavity 8, electrode 6,7, working air current 12, speculum 13, outgoing mirror 14.The optical cavity that it is characterized in that laser is for circular, and the chamber wall is a metal.Whole cylindrical cavity 8 is divided into two sections, and the entrance channel 4 of each section is positioned at same plane with the center line of outlet flow 5, and outlet flow 5 center lines are with respect to angle of entrance channel 4 center line deflections; Two sections entrance channel 4 is uniform on the circumference of cylindrical cavity 8, becomes 180 degree, and rotation direction is identical.
Working air current 12 is produced by blower fan 2, in entrance channel 4 enters cylindrical cavity 8.Because the outlet flow 5 of cylindrical cavity 8 working air current 12 rotates respective angles in cylindrical cavity 8 after, outside outlet flow 5 exhaust chambers, is then got back to blower fan 2 by heat exchanger 3 with respect to entrance channel 4 deflections 110 degree, circulates.
An electrode of the laser of present embodiment is made up of the electrode unit of a plurality of mutually insulateds and tool air cooling runner.Another electrode is the overall structure with water-cooled runner.
Laser structure of the present utility model is applicable to carbon dioxide laser and CO (carbon monoxide converter) laser.
Claims (4)
