Detailed Implementation

[0030] To make the technical solution of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, such as... Figures 1 to 7 The device includes a water-cooled base 1, with a positive electrode 4 and a negative electrode 5 installed at both ends. Multiple laser modules A6 and B7 are installed in the middle of the water-cooled base 1. Laser modules A6 and B7 are connected by a circuit connecting piece 8 and a fastening bolt 9. This device connects laser modules A6 and B7 via a circuit connecting piece 8, which is fixed by the fastening bolt 9. This allows for replacement of the laser module by removing the fastening bolt 9 when it is damaged, improving maintenance convenience. Laser modules A6 and B7 are composed of multiple small modules, suitable for use in spaces of different sizes, thus improving versatility.

[0031] The bottom of the water-cooled base 1 is equipped with an inlet pipe 2 and an outlet pipe 3. The inlet pipe 2 is used for the entry of water-based coolant, and the outlet pipe 3 is used for the discharge of water-based coolant.

[0032] Fastening bolt 9 is an anti-loosening bolt, which is used to prevent loosening of the connecting parts.

[0033] The laser module A6 has two connection holes 10 on one end and two connection holes 11 on the other end. The two connection holes 10 and the two connection holes 11 are used for fixing the connecting components and for power supply.

[0034] The top of the laser module A6 is equipped with multiple laser units 14, which work to emit laser light and enable the laser module A6 to operate. The laser module A6 encapsulates 252 laser working particles, each with an operating voltage of 3.5V, an operating current of 4A, an output laser power of 3W, and a laser wavelength of 940nm. According to the series-parallel connection relationship shown in the figure, it is easy to find that the operating voltage of each module is 49V, the operating current is 72A, and the output laser power is 756W.

[0035] Laser module B7 has two connection holes 13 on one end and two connection holes 12 on the other end. These holes are used for fixing and powering the connected components. Using 21 laser modules A6 and 21 laser modules B7, a laser output exceeding 30kW can be achieved. Laser module B7 encapsulates 252 laser working particles, each with a working voltage of 3.5V, a working current of 4A, an output laser power of 3W, and a laser wavelength of 940nm. Based on the series-parallel connection diagram, it is easy to deduce that each module has a working voltage of 49V, a working current of 72A, and can output a laser power of 756W.

[0036] Multiple laser units 14 are mounted on the top of the laser module B7. The multiple laser units 14 work to emit laser light, so that the laser module B7 can work.

[0037] The laser unit 14 has a metal pin 15 at its outer end, which is used to fix the laser unit 14 and to power it.

[0038] The implementation principle of a modular water-cooled laser in this application embodiment is as follows: When a modular water-cooled laser is used, the basic module is divided into two types: laser module A6 and laser module B7. The two types of electrode directions are mirror symmetrical. The module is based on a ceramic-based circuit board, and its upper surface is encapsulated with several surface-emitting laser particles. The module can be easily integrated through series and parallel connections and fixed by circuit connecting pieces 8 and fastening bolts 9 to obtain a large-size laser device.

[0039] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
