Problems solved by technology
[0004] As mentioned above, the indicator light provided by the laser in the prior art is usually a solid spot, the outer edge of which does not necessarily coincide with the outer edge of the spot formed by the working light source or its boundary is not clear, which will cause the operation The operator cannot know the actual size of the light spot formed by the working light source and its edge range, so that the operator cannot accurately determine the working area that needs to be processed

Embodiment Construction
[0027] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0028] Such as figure 1 As shown, the embodiment of the present invention provides a laser 10 for generating ring-shaped indicating light, including a main laser source 11, an indicating light source 12 and a focusing lens 13, wherein:
[0029] The light beam emitted by the main laser source 11 and the light beam emitted by the indicator light source 12 respectively enter the focusing lens 13 and are focused by the focusing lens 13;
[0030] The maximum distance from the light spot formed on the surface of the focusing lens 13 by the light beam emitted by the indicating light source 12 to the center of the focusing lens 13 is not less than the light spot formed on the surface of the focusing lens 13 by the light beam emitted by the mai...

The invention discloses a laser device for generating ring-shaped indicating light, which includes a main laser source, an indicating light source and a focusing lens, wherein: the light beam emitted by the main laser source and the indicating light source are respectively incident on the focusing lens, and the The focus lens is focused; the maximum distance from the light spot formed on the surface of the focus lens by the light beam emitted by the indicating light source to the center of the focus lens is not less than the distance from the light spot formed on the surface of the focus lens by the light beam emitted by the main laser source The distance from the light spot to the center of the focusing lens is used in the present invention to generate a ring-shaped indicator light, so as to realize the clear division of the working area and the non-working area.
Description
technical field [0001] The invention relates to the technical field of lasers, in particular to a laser generating ring-shaped indicating light. Background technique [0002] In the fields of industry, medicine and scientific research, infrared lasers with a central wavelength of 915nm, 980nm, 1064nm or 1470nm are often used as working light sources. The above-mentioned working light sources are invisible light; but in practical applications, it is usually necessary to know the exact irradiation position of the above-mentioned working light sources And the irradiation range, therefore, it is necessary to use visible wavelength light as the indicating light source for indicating and guiding. [0003] Lasers in the prior art usually add another laser and the corresponding coupling fiber or coupling lens system to achieve the purpose of providing indicator light, or use a dichroic mirror to couple the working light source and the indicator light source, so that it can be output...
