Description

Technical Field

[0001] This utility model relates to the field of laser technology, and in particular to a multi-core laser tube with a square outer tube and a carbon dioxide laser. Background Technology

[0002] A carbon dioxide laser consists of a gas storage tube containing carbon dioxide and other gases. The two ends of the storage tube serve as mounting points for the laser within the laser machine. The storage tube also acts as a mounting frame for the reflecting and output mirrors. In a carbon dioxide laser, when a high voltage is applied to the electrodes, a glow discharge is generated in the discharge tube. This glow discharge is reflected by the resonant cavity formed by the reflecting mirror, the discharge tube, and the output mirror, forming a laser beam that exits from the output mirror. It has found wide applications in mechanical, military, medical, and chemical industries.

[0003] Currently, the gas storage tubes of multi-core laser tubes are all circular tubes of equal diameter. Two or more discharge tubes and water cooling tubes are housed within the circular tube shell. This internal folding within the same shell extends the length of the discharge tubes, achieving high power output. An example is a large-tube multi-core carbon dioxide laser tube (CN106253034A). To increase the gas storage capacity of multi-core laser tubes, the diameter of the gas storage tube is typically increased without increasing its length. This method increases both the laser beam intensity and the amount of carbon dioxide gas stored, while ensuring a reduction in the effective attenuation of carbon dioxide gas within the storage tube. This stabilizes the output power of the carbon dioxide laser and significantly extends its lifespan, resulting in a substantial increase in the laser's overall lifespan.

[0004] However, due to the increased diameter of the gas storage tube, the diameter of the mounting end of the carbon dioxide laser tube also increases, ultimately requiring the size of the mounting base for the carbon dioxide laser in the laser machine to be refitted with the increased diameter of the gas storage tube. Furthermore, existing high-power multi-mirror folded cavity lasers generally use multiple glass tubes arranged in parallel. This presents the following problems: the production process involves connecting and sealing the tubes with elbows at both ends; the increased width after multiple parallel arrangements places greater demands on the installation space; and the need for adhesive bases for fixation increases the weight of the adhesive bases. Additionally, during installation, the discharge tubes within the multi-core laser tube need to be horizontal; otherwise, the optical path will be unstable, easily affecting the beam pattern. Traditional circular multi-core laser tubes require multiple adjustments to keep the discharge tubes horizontal, reducing the installation efficiency and operational stability of the multi-core laser tube. Utility Model Content

The tube is characterized by further comprising a square columnar gas storage tube, with n connecting tubes at both ends. Each connecting tube has a terminal block. The n discharge tubes are arranged in an array within the gas storage tube, and their positive and negative terminals are electrically connected to the corresponding terminals via wires. Each discharge tube is fitted with a water-cooling tube, and each water-cooling tube has return gas tubes fitted at both ends. Two return gas tubes are connected to the terminals of the discharge tubes at one end and to the gas storage tube at the other end.

[0008] As a preferred technical solution of this utility model, n is an integer greater than or equal to 2, and n water inlet pipes and n water outlet pipes are respectively provided at both ends of the outer wall of the gas storage pipe, and each water cooling pipe is connected to the corresponding water inlet pipe and the corresponding water outlet pipe.

Detailed Implementation

[0025] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0026] In the attached diagram, all identical reference numerals refer to the same components.

[0027] Example 1:

[0028] like Figure 1-6As shown, this utility model provides a multi-core laser tube with a square outer tube, including n discharge tubes 300, which are spaced apart. The feature is that it also includes a square columnar gas storage tube 100, with n connecting tubes 120 at both ends of the gas storage tube 100. Each connecting tube 120 has a terminal 110. The n discharge tubes 300 are arranged in an array inside the gas storage tube 100, and the positive and negative terminals at both ends are electrically connected to the corresponding terminals 110 via wires. Each discharge tube 300 is fitted with a water-cooling tube 200, and each water-cooling tube 200 has return gas tubes 400 fitted at both ends. The two return gas tubes 400 are connected to the electrode of the discharge tube 300 at one end and to the gas storage tube 100 at the other end.

[0029] In this embodiment, a multi-core laser tube is formed by installing n discharge tubes 300 and water-cooling tubes 200 and return gas tubes 400 in a square columnar gas storage tube 100.

[0030] The positive and negative terminals at both ends of each discharge tube 300 are electrically connected to the corresponding terminals 110 on the connecting pipes 120 at both ends of the gas storage pipe 100 via wires to energize the discharge tube 300.

[0031] The water-cooling pipe 200 is connected to an external chiller via a pipeline to cool the laser tube, and the return gas pipe 400 is used for return gas.

[0032] Furthermore, the gas storage pipe 100 is a square column-shaped glass tube.

[0033] In this embodiment, the rectangular gas storage tube 100 can increase the gas storage capacity with the same space occupation. Under suitable conditions, it can be installed without a support (the side wall is flat and will not roll like a round tube), saving the cost and weight of the support compared to a round tube. It can also make the installation of multi-core laser tubes more precise, allowing the discharge tube 300 to be adjusted to a horizontal position more quickly during installation, making it easier to place the discharge tube 300 horizontally after installation, thereby making the laser beam path more stable. Unlike when using a round tube, there is no need to adjust the discharge tube 300 inside the tube multiple times, thus improving the installation efficiency.

[0034] The edges of the square-shaped gas storage pipe 100 can be rounded.

[0035] Furthermore, n is an integer greater than or equal to 2. The two ends of the outer wall of the gas storage pipe 100 are respectively provided with n water inlet pipes 210 and n water outlet pipes 220, and each water cooling pipe 200 is connected to the corresponding water inlet pipe 210 and the corresponding water outlet pipe 220.

[0036] In this embodiment, the laser tube is connected to an external chiller through the corresponding inlet pipe 210 and the corresponding outlet pipe 220 to cool it down.

[0037] Furthermore, when n=2, the two discharge tubes 300 can be arranged symmetrically within the gas storage tube 100.

[0038] In this embodiment, two discharge tubes 300 form a multi-core structure inside the gas storage tube 100, and when connected, they can generate higher power lasers.

[0039] Example 2:

[0040] The rest is the same as in Example 1. When n=3, the three discharge tubes 300 can be arranged in a straight line within the gas storage tube 100.

[0041] Example 3:

[0042] The rest is the same as in Example 1. When n=4, the four discharge tubes 300 can be arranged in a straight line within the gas storage tube 100.

[0043] Example 4:

[0044] The rest is the same as in Example 1. When n=4, the four discharge tubes 300 can be arranged in a grid pattern inside the gas storage tube 100.

[0045] Example 5:

[0046] A light outlet 500 and a tail mirror 600 are respectively installed on two connecting pipes 120 at one end of the gas storage pipe 100. The light outlet 500 is used to output laser. The remaining connecting pipes 120 are connected in pairs without overlap through the connecting unit 700 so that a light path is formed from the tail mirror 600 to the light outlet 500.

[0047] The connecting unit 700 includes a U-shaped tube 710. The two ports of the U-shaped tube 710 are respectively connected to the ends of two corresponding connecting tubes 120. The bends of the U-shaped tube 710 are provided with total reflection mirrors 720 to reflect light, thereby forming a light path so that the laser can be emitted from the light outlet 500.

[0048] Example 6:

[0049] like Figure 6 As shown, this utility model provides a carbon dioxide laser, including a plurality of multi-core laser tubes 800 with a square outer tube, and the sidewalls of the plurality of multi-core laser tubes 800 are connected to each other to form an array structure.

[0050] In this embodiment, a multi-core laser tube with multiple square outer tubes is combined to obtain a carbon dioxide laser with higher power.

[0051] The combined carbon dioxide laser has an output port 500 and a tail mirror 600. The output port 500 and the tail mirror 600 are mounted on corresponding connecting tubes 120. The connecting tubes 120 in the remaining multi-core laser 800 are connected in pairs without repetition through the connecting unit 700 so that an optical path is formed from the tail mirror 600 to the output port 500.

[0052] Furthermore, multiple multi-core laser tubes 800 are connected together using adhesive.

[0053] In this embodiment, the sidewalls of multiple multi-core laser tubes 800 are connected by adhesive to achieve the purpose of fixation.

[0054] This invention relates to a multi-core laser tube with a square outer tube. The use of a square columnar gas storage tube increases the gas storage capacity, allows for more precise installation of the multi-core laser tube, and facilitates the horizontal placement of the discharge tube after installation, thereby making the laser's optical path more stable. The square columnar gas storage tube also allows multiple multi-core laser tubes to be tightly and seamlessly bonded together, resulting in a more compact and stable structure and a laser that saves installation space.
