Description

Technical Field

[0001] This utility model relates to the field of optical equipment technology, and in particular to a lens metal adjustment head for a folded laser. Background Technology

[0002] Folded lasers fold the laser beam path using components such as optical mirrors, enabling the laser to propagate a longer effective optical path within a limited space. This enhances the interaction between the laser and the gain medium, thereby increasing the laser's output power and gain efficiency.

[0003] Existing laser tube lenses generally do not come with adjustable heads. During the manufacturing process of laser tubes, the glass tube opening angle is usually pre-polished before the lens is directly attached.

[0004] However, when dealing with high-power laser tubes, a significant power error becomes apparent, and this error increases with the power of the laser tube. At the same time, poor beam quality also occurs. Since there is no adjustable head, it is inconvenient to make corresponding adjustments to the beam. Therefore, a metal adjustment head for the lens of a folded laser is proposed to solve the above problems. Utility Model Content

[0006] To address the technical problems existing in the background art, this utility model proposes a metal adjustment head for a folded laser lens. By adjusting the depth of the adjustment head in the threaded hole, the lens angle can be finely adjusted, thereby correcting the spot quality and improving the laser power.

[0007] (II) Technical Solution

[0008] This utility model provides a metal adjustment head for a folded laser lens, including an adjustment head body. The adjustment head body includes a metal ring and a mounting sleeve. The multiple metal rings are equidistantly distributed, and adjacent metal rings are connected by the mounting sleeve.

[0009] A lens mounting tube is coaxially connected to the left end face of the metal ring on the left side, and multiple threaded holes are arranged in a ring array on the left end face of the metal ring on the left side. An adjusting component is connected to the internal thread of the threaded hole.

[0010] A lens mounting groove is provided on the left side of the lens mounting tube, and a lens is mounted on the inner end face of the lens mounting groove.

[0011] Preferably, there are three metal rings and six threaded holes.

[0012] Preferably, the adjusting member includes a connecting bolt, which is threaded into the inside of the threaded hole, and the adjusting head of the connecting bolt is close to the side of the lens.

[0026] like Figure 1-4 As shown, the present invention proposes a metal adjustment head for a folded laser lens, comprising an adjustment head body, which includes metal rings 5 ​​and mounting sleeves 6. Multiple metal rings 5 ​​are equidistantly distributed, and adjacent metal rings 5 ​​are connected by the mounting sleeves 6. A lens mounting tube 2 is coaxially connected to the left end face of the left metal ring 5. Multiple threaded holes 7 are arranged in a ring array on the left end face of the left metal ring 5. Adjusting components are threaded into the internal parts of the threaded holes 7. Through the cooperation of the threaded holes 7 and the adjusting components, the angle of the lens 1 can be finely adjusted, thereby correcting the spot quality and increasing the laser power. A lens mounting groove 8 is provided on the left side of the lens mounting tube 2. A lens 1 is mounted on the inner end face of the lens mounting groove 8. There are three metal rings 5 ​​and six threaded holes 7.

[0027] In this invention, when in use, the lens 1 is first installed on the lens mounting groove 8 with glue, and the rightmost metal ring 5 is glued to the glass tube opening of the folding laser. This allows the adjustment head to be adjusted at the depth of the threaded hole 7 to finely adjust the angle of the lens 1, thereby correcting the spot quality and increasing the laser power.

[0028] In an optional embodiment, the adjusting member includes a connecting bolt 3, which is threaded into the inside of a threaded hole 7, and the adjusting head of the connecting bolt 3 is located near the side of the lens 1.

[0029] It should be noted that the connecting bolt 3 is threaded into the threaded hole 7, and its adjusting head is close to the side of the lens, which makes it easy to adjust the angle of the lens 1 by rotating the connecting bolt 3.

[0030] In an optional embodiment, a conical block 4 is also included, which is located at the right end of the connecting bolt 3.

[0031] It should be noted that when the connecting bolt 3 is rotated, it can drive the conical block 4 to rotate. The conical block 4 abuts against the left side of the middle metal ring 5, thereby enabling fine adjustment of the angle of the lens 1.

[0032] In an optional embodiment, the inner diameter of the lens mounting groove 8 is slightly larger than the radius of the lens 1.

[0033] It should be noted that the inner diameter of the lens mounting groove 8 is slightly larger than the radius of the lens 1. This ensures that the lens 1 can be securely installed in the lens mounting groove 8, while also preventing the lens 1 from being damaged due to excessive tightness.

[0034] In an optional embodiment, the lens mounting tube 2, the metal ring 5, and the mounting sleeve 6 are all annular structures.

[0035] It should be understood that the above-described specific embodiments of the present invention are merely illustrative of or explanation of the principles of the present invention and do not constitute limitations of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention shall be included within the scope of protection of the present invention.
