Fig. 2 is the partial enlarged view of antidetonation protection type laser.
Fig. 3 is the diagrammatic cross-section of magnetic conductive metal cover outer wall convex edge.
Specific embodiment
The technical issues of in order to keep the utility model solved, technical solution and beneficial effect are more clearly understood, below
In conjunction with the embodiments and attached drawing, the present invention will be further described in detail.It should be appreciated that specific implementation described herein
Example is only used to explain the utility model, is not used to limit the utility model.
See that Fig. 1, laser include shell, laser bar 2 is equipped in shell, laser is projected from the light emission side of laser bar 2, is being swashed
Optical wand 2 goes out in light optical path, should go out light optical path and be disposed with Q-switch 3, laser pump (ing) 4, output lens 5, shell is equipped with
Light hole, output lens 5 are directed at light hole, and laser is projected from light hole.It is additionally provided with and is all-trans on the opposite direction of light optical path out
Mirror 1 is penetrated, laser reflection is returned Q-switch 3 by total reflection mirror 1.
See Fig. 2, columned magnetic conductive metal cover 31 is additionally provided in shell, magnetic conductive metal cover 31 covers the Q-switch 3, leads
It is opened on the side wall of magnetic metal cap 31 there are two through-hole 32, through-hole 32 is opened in out in light optical path, and the laser projected by laser bar 2 is through logical
Cross magnetic conductive metal cover 31 in hole 32.Fin 33 is distributed on the lateral wall of magnetic conductive metal cover 31, fin 33 is along magnetic conductive metal cover 31
Extend radially out and around the peripheral side helical arrangement of magnetic conductive metal cover 31, fin 33 is continuous uninterrupted.In use, in Q-switch 3
Radio-frequency power supply works after generated electromagnetic wave is absorbed by magnetic conductive metal cover 31 and is lost, and electromagnetic wave is avoided to overflow outside Q-switch 3；
In the radio-frequency power supply course of work, since fin 33 increases the contact area of magnetic conductive metal cover 31 lateral wall and air, therefore energy
Magnetic conductive metal cover 31 is accelerated to radiate.In addition, by the way that the shape of magnetic conductive metal cover 31 is set as cylindric, and make fin 33 along magnetic conduction
Around the peripheral side spiral of magnetic conductive metal cover 31 after the extending radially out of metal cap 31, in this way, fin 33 be it is continuous continual,
Therefore wedge angle is all not present in the surface of fin 33 and magnetic conductive metal cover 31, to avoid fin 33 and magnetic conductive metal cover 31 in electromagnetic wave
