Abstract
Description
Technical Field
[0001] The present application relates to the field of aperture technology, and specifically to a water-cooled aperture. Background Art
[0002] An aperture is an entity that limits the beam in an optical system. In lasers, the use of an aperture is a common method of beam shaping, which can adjust the shape and size of the beam. An aperture is a physical aperture or opening used to limit and adjust the beam. By controlling the shape and size of the aperture, the cross-sectional shape and size of the beam can be adjusted to achieve specific optical performance.
[0003] For example, the utility model patent with publication number CN217543431U specifically discloses an aperture, a base and an aperture assembly. When in use, it is only necessary to rotate the rotating part to the corresponding light-transmitting position according to the beam size requirements, so that the light beam passes through the light-transmitting hole of the corresponding diameter, effectively increasing the application range of the adjustable aperture, so that the adjustable aperture can be applied to laser amplifiers with greater uncontrollability.
[0004] In the above patent, the device increases the applicable range of the adjustable aperture by setting a rotatable and adjustable rotating part so that the rotating part changes the light transmission position. However, since the rotating part is made of aluminum plate or copper with good thermal conductivity, when light is irradiated onto the rotating part, the stray light hitting the plane and the reflected light may return along the original path. Since the stray light also has a certain power, when it is irradiated onto the aluminum plate, if there is no good heat dissipation, the heat will be superimposed, causing the aluminum plate to become hot and deformed, etc., which will eventually affect the light path. Therefore, it is necessary to provide a water-cooled aperture with a cooling function to solve the above problem.
[0005] It should be noted that the above information disclosed in this background technology section is only for understanding the background technology of the present application concept, and therefore, it may contain information that does not constitute the prior art. Summary of the invention

[0008] Furthermore, the aperture assembly includes an aperture body, the aperture body has a fixing plate, an irradiation plate is extended from one side of the fixing plate, and the aperture hole is installed on the irradiation plate.
[0009] Furthermore, the incident surface of the aperture is provided with a bell mouth.
[0010] Furthermore, a slide groove is provided on one side of the water-cooling base, a slider is slidably connected in the slide groove, a threaded hole is provided on the slider, and a through hole matching the size of the threaded hole is correspondingly provided on the fixing plate.

[0012] Furthermore, the aperture assembly and the water-cooling base are both made of copper material.
[0013] The beneficial effect of the present application is that a water-cooled aperture provided by the present application, by setting a water-cooling component, ensures that the aperture component will not cause material deformation due to overheating during operation, thereby affecting the irradiation effect. At the same time, by setting a fine-tuning component, the aperture component can be adjusted according to the irradiation direction of the laser beam, further increasing the practicality of the device.

[0023] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0024] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.
[0025] like Figure 1-Figure 2 As shown, the present application provides a water-cooled aperture, including a laser 1, the laser 1 having a hollow cavity, and a water-cooled base 3 is arranged on the laser 1, the water-cooled base 3 penetrates the laser 1 and is fixedly installed on the outside of the laser 1, and a sealing ring is arranged between the two, and an aperture assembly 2 is arranged on the laser 1, the aperture assembly 2 is used to control the propagation of the laser beam, and the aperture assembly 2 and the water-cooled base 3 are both made of copper material with high thermal conductivity;
[0026] The water-cooling base 3 is provided with a water-cooling assembly inside, and the water-cooling assembly includes a V-shaped water channel 33, and a water inlet hole 34 and a water outlet hole 35 are provided at the bottom of the water channel 33, wherein the water inlet hole 34 is suitable for being connected to an external water inlet pipe, so that external cooling water enters the water channel 33 through the water inlet hole 34, and the water outlet hole 35 is suitable for being connected to an external water outlet pipe, so that the cooling water in the water channel 33 can be discharged in time;
[0027] When irradiation begins, cooling water enters the water channel 33 through the water inlet 34, and then continues to flow inside the water channel 33 and continuously cools the device, effectively absorbing the heat generated by laser light irradiation and keeping the temperature of the aperture assembly 2 within an acceptable range.
[0028] like Figure 3-Figure 5 As shown, a slide groove 31 is provided on one side of the water-cooled base 3, and the aperture assembly 2 is installed in the slide groove 31. The aperture assembly 2 includes an aperture body 21, and the aperture body 21 has a fixing plate 211. At the same time, an irradiation plate 212 is extended and provided on one side of the fixing plate 211. An aperture hole 22 is provided at the center of the irradiation plate 212. The aperture hole 22 is used for the laser beam to pass through, and the water-cooled base 3 and the laser beam form an angle of 30°;
[0029] At the same time, a bell mouth 221 is provided on the incident surface of the aperture 22. When the returning light encounters the bell mouth 221, it will not return along the original path, but will scatter outward, thereby reducing the risk of the returning light causing damage to the device in front of the optical path.
[0030] At the same time, multiple groups of sliders 32 are slidably connected in the slide groove 31, and threaded holes are set on the sliders 32. At the same time, through holes matching the size of the threaded holes are correspondingly set on the fixed plate 211. During installation, the fixed plate 211 and the sliders 32 are connected by bolts, so that the aperture body 21 is connected to the water-cooled base 3 and is suitable for moving in the slide groove 31. At the same time, the contact surfaces between the aperture body 21 and the water-cooled base 3 remain smooth and flat, which is beneficial to heat conduction.
[0031] At the same time, a fine-tuning component is arranged on the water-cooling base 3, and the fine-tuning component includes a scale mark 4, and the scale mark 4 is installed above the slide groove 31. At the same time, an indication arrow 41 is arranged on the fixed plate 211 corresponding to the scale mark 4. The user can fine-tune the aperture assembly 2 on the water-cooling base 3 left and right with the cooperation of the scale mark 4 and the indication arrow 41. During the fine-tuning process, the aperture hole 22 will also move left and right in the vertical direction of the light beam to achieve the effect of being concentric with the light beam.
[0032] In summary, the device sets a water cooling component so that the aperture component 2 will not deform due to overheating during operation, thereby affecting the irradiation effect. At the same time, by setting a fine-tuning component, the aperture component 2 can be adjusted according to the irradiation direction of the laser beam, further increasing the practicality of the device.
