Background

When the laser device detects laser energy, a detection surface of the energy meter needs to be arranged towards the laser emitting direction, partial laser reflection can occur when the laser irradiates on the detection surface, if the detection surface faces the laser emitting direction, the reflected laser is likely to return along the emitting direction, and the returned laser and the emitted laser can be dried, so that the energy detection accuracy of the laser is affected.

In the prior art, in order to avoid that reflected laser returns along an original emergent light path to influence detection accuracy, a complex light path structure is generally designed to guide the emergent laser, and chinese patent CN211234721U discloses an energy detection device, which adopts a series of light path guiding structures to cooperate with the detection device.

All other embodiments, which can be made by those skilled in the art based on the embodiments of the present utility model without making any inventive effort, are intended to fall within the scope of the present utility model.

It will be understood that when an element is referred to as being "mounted" or "disposed" on another element, it can be directly on the other element or be indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or be indirectly connected to the other element.

It is to be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like indicate or are based on the orientation or positional relationship shown in the drawings, merely to facilitate description of the present application and simplify description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be configured and operated in a particular orientation, and therefore should not be construed as limiting the present application.

Furthermore, the terms "first," "second," and the like, are used for descriptive purposes only and are not to be construed as indicating or implying a relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature. In the description of the present application, the meaning of "a plurality" is two or more, unless explicitly defined otherwise.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which embodiments of the utility model belong. If the definitions set forth in this section are contrary to or otherwise inconsistent with the definitions set forth in the patents, patent applications, published patent applications and other publications incorporated herein by reference, the definitions set forth in this section are preferentially set forth in the definitions set forth herein.

As shown in fig. 1, referring to fig. 2-4, the laser energy detection auxiliary device of the present utility model includes a barrel 1, the barrel 1 is penetrated along an axis direction to form a light-emitting channel 11, two ends of the light-emitting channel 11 are respectively provided with a first opening 12 and a second opening 13, a plane of the first opening 12 is perpendicular to the axis of the light-emitting channel 11, and an included angle between a plane of the second opening 13 and a plane of the first opening 12 is an acute angle.

In the above embodiment, the first opening 12 is used to face the laser emission port, the light emission channel 11 is used for passing laser, the second opening 13 is used to support the laser energy meter, and since the planes of the first opening 12 and the second opening 13 are acute angles, most of reflected laser formed by the laser emitted to the detection surface of the laser energy meter after reflection will not directly return along the light path of the emitted laser, so that the interference problem between the emitted laser and the reflected laser is greatly reduced, and the detection accuracy of the laser energy meter is improved.

In some embodiments, the angle between the plane of the first opening 12 and the plane of the second opening 13 is 0-10 °.

In the above embodiment, the included angle between the plane of the first opening 12 and the plane of the second opening 13 should be avoided from being too large, and the too large included angle easily affects the receiving effect of the laser energy meter on the laser, and as a preferred range, the included angle is between 0 ° and 10 °.

In some embodiments, the angle between the plane of the first opening 12 and the plane of the second opening 13 is 2-8 °.

In the above embodiments, as a more preferable embodiment, when the included angle between the plane in which the first opening 12 is located and the plane in which the second opening 13 is located is 2 ° to 8 °, the laser receiving effect of the laser energy meter can be considered, and the coherent interference of the reflected laser light and the emitted laser light can be prevented.

In some embodiments, the angle between the plane of the first opening 12 and the plane of the second opening 13 is 6 °.

In some embodiments, the aspect ratio of the light exit channel 11 is 1-2.

In the above embodiment, the larger the diameter of the light-emitting channel 11 is, the smaller the interference effect of the reflected light on the emitted laser light is, but the larger the diameter is, the more difficult the matching with the laser energy meter is, when the light-emitting channel 11 is longer, the reflected laser light is easily reflected on the inner wall of the light-emitting channel 11, increasing the risk of interference, and when the light-emitting channel 11 is shorter, the reflected light is easily reflected directly to the surface of the laser light emitting device, causing unnecessary damage, therefore, the preferred embodiment is that the length-diameter ratio of the light-emitting channel 11 is 1-2.

In some embodiments, the aspect ratio of the light exit channel 11 is 1.2-1.8.

In some embodiments, the inner side surface of the light-emitting channel 11 is provided with at least one light-emitting opening 14.

In the above embodiment, the light outlet 14 can let the reflected laser light emit, so as to reduce the risk of coherent interference caused by multiple reflections of the reflected laser light in the light outlet channel 11.

In some embodiments, the number of light outlets 14 is not less than two, and a plurality of light outlets 14 are arranged along the circumferential surface array of the light outlet channel 11, and adjacent light outlets 14 are arranged at intervals.

In the above embodiment, the plurality of light outlets 14 can further reduce the coherent interference of the reflected laser, and also can avoid the damage of the reflected laser to the light outlet channel 11, and the structural strength of the cylinder 1 can be improved by the struts formed between the light outlets 14 arranged at intervals.

In some embodiments, the light outlet 14 is formed at a position where the common normal plane of the first opening 12 and the plane of the second opening 13 intersects the inner surface of the light outlet channel 11.

In the above embodiment, most of the reflected laser light propagates along the common normal plane of the first opening 12 and the plane of the second opening 13 after being reflected by the reflecting surface of the laser energy meter, so that the light outlet 14 is formed at the place where the common normal plane passes, and the reflection of the reflected laser light in the light outlet channel 11 can be avoided to a great extent, so that most of the reflected light interference is reduced.

The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the utility model.
