Abstract
Description
Technical Field
[0001] This invention relates to the field of laser technology, and in particular to a giant pulse laser with adjustable pulse width. Background Technology
[0002] A giant pulse laser with adjustable pulse width is a device that can flexibly control the width of the output laser pulse. It uses Q-switching technology to build a loss mechanism in the cavity and controls the timing of switching between high-loss and low-loss states to adjust the pulse width in the range of nanoseconds to microseconds. When a high energy peak is required, the pulse width can be shortened to increase the power, and if a specific action time is desired, the pulse width can be extended.
[0003] The housing of adjustable pulse width giant pulse lasers is mostly made of high-strength metal integrated structure. The laser head mounting part is rigidly fixed to the internal optical path bracket by precision slots and bolt groups. When replacing, it is necessary to first remove the multi-layer protective plate on the side of the housing, disconnect the water cooling pipe and dustproof air curtain assembly bound to the laser head, and then loosen the micron-level adjustment bolts with special tools.
[0004] Existing giant pulse laser devices with adjustable pulse widths suffer from low maintenance efficiency in scenarios requiring rapid laser head switching. Frequent disassembly and assembly may also damage the sealing performance of the housing, increase the risk of dust intrusion, and affect the stability of pulse width adjustment. Therefore, a giant pulse laser with adjustable pulse width is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this invention provides a giant pulse laser with adjustable pulse width, aiming to improve the problem that the housing cannot be quickly replaced with laser head circuitry in the prior art.

A rotating rod is slidably connected to the outer wall of the limiting post. A fixed rod is fixedly connected to the bottom of the rotating rod. A sliding post is slidably connected to the inner wall of the rotating rod. A scraper is fixedly connected to the other end of the sliding post.
[0012] As a further description of the above technical solution:
[0013] A data cable is slidably connected inside the connecting ring, and an adapter block is fixedly connected to the other end of the data cable. A laser head is fixedly connected to the outside of the adapter block.
[0014] As a further description of the above technical solution:

[0022] This utility model has the following beneficial effects:
[0023] 1. In this utility model, when the laser head is damaged due to long-term use of the laser and needs to be replaced, the data cable is pulled outward, which causes the connecting ring to move outward. The connecting ring moves the locking ring through the ball, allowing the ball to disengage from the fixing ring and move into the locking ring. The connecting ring drives the data cable to disengage to complete the replacement. After replacement, the data cable is pushed, and the connecting ring is locked onto the locking ring by the ball.
[0024] 2. In this utility model, when the laser generates dust, the starting motor drives the disc to rotate. The rotation of the disc causes the limiting column to rotate around its axis. The limiting column drives the rotating rod to swing back and forth. The sliding column slides in the groove of the rotating rod, causing the scraper to move back and forth in a straight line along the surface of the filter plate, continuously cleaning the dust on the surface of the filter plate, ensuring the cleanliness and normal operation of the equipment.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0034] Reference Figure 3 , Figure 5 and Figure 6 This utility model provides an embodiment of a giant pulse laser with adjustable pulse width, comprising a housing 1. A fixing ring 20 is fixedly connected inside the housing 1. A locking ring 24 is slidably connected to the inner wall of the fixing ring 20, sliding within the fixing ring 20. A spring 23 is sleeved on the outer wall of the locking ring 24, providing elastic potential energy to ensure a tight fit between the locking ring 24 and the inner wall of the fixing ring 20. A connecting ring 21 is slidably connected to the inner wall of the locking ring 24, and the connecting ring 21 can move within the locking ring 24. A ball 22 is slidably connected inside the connecting ring 21, and the ball 22 slides within the connecting ring 21. A disassembly assembly is provided on the outside of the housing 1, including a pressing block 18. A fixing block 13 is fixedly connected to the outside of the housing 1, and a second spring 17 is fixedly connected inside the fixing block 13. The second spring 17 generates elastic potential energy, and a locking block 16 is fixedly connected to the other end of the second spring 17. The second spring 17 releases elastic potential energy onto the locking block 16, supporting the locking block 16. A first spring 14 is fixedly connected inside the fixing block 13. Spring 14 generates elastic potential energy. A fixed post 15 is fixedly connected to the other end of spring 14, providing elastic force to support the fixed post 15. A filter plate 5 is movably connected to the outside of the housing 1. A connecting block 19 is fixedly connected to the outer wall of the filter plate 5. The inside of the connecting block 19 contacts the top of the locking block 16. The top of the locking block 16 is embedded in the groove of the connecting block 19, forming a horizontal constraint to prevent the filter plate 5 from moving laterally or detaching from the housing 1. The bottom of the connecting block 19 is connected to the top of the fixed post 15. When the top of the fixed post 15 presses against the bottom of the connecting block 19, the spring 14 releases its elastic potential energy, squeezing the fixed post 15, thereby squeezing the connecting block 19, making the connecting block 19 more firmly engaged with the locking block 16. The bottom of the pressing block 18 contacts the outside of the locking block 16. When the pressing block 18 is pressed, the bottom of the pressing block 18 squeezes the inclined surface of the locking block 16, and the top of the locking block 16 disengages from the groove of the connecting block 19. The pressing block 18 is slidably connected to the inside of the fixed block 13, and the ball 22 is slidably connected to the inside of the locking ring 24.
[0035] Reference Figure 1 , Figure 2 and Figure 4A motor 7 is fixedly connected inside the housing 1. A disc 8 is fixedly connected to the drive end of the motor 7. The movement of the motor 7 drives the disc 8 to rotate synchronously. A limiting post 9 is fixedly connected to the outer wall of the disc 8. The limiting post 9 rotates synchronously with the disc 8. A rotating rod 11 is slidably connected to the outer wall of the limiting post 9. A fixed rod 10 is fixedly connected to the bottom of the rotating rod 11. The rotating rod 11 is sleeved on the outside of the limiting post 9. When the disc 8 rotates, the limiting post 9 slides in the groove of the rotating rod 11, driving the rotating rod 11 to swing around the fixed rod 10. A sliding post 12 is slidably connected to the inner wall of the rotating rod 11. The sliding column 12 slides inside the groove, and a scraper 6 is fixedly connected to the other end of the sliding column 12. The movement of the sliding column 12 drives the scraper 6 to move. A data cable 2 is slidably connected inside the connecting ring 21. The data cable 2 is used to control signals or energy. An adapter block 3 is fixedly connected to the other end of the data cable 2. A laser head 4 is fixedly connected to the outside of the adapter block 3. The adapter block 3 serves as the interface between the data cable 2 and the laser head 4, transmitting the signals or energy of the data cable 2 to the laser head 4. The outside of the scraper 6 is in contact with the outside of the filter plate 5. The edge of the scraper 6 is close to the surface of the filter plate 5. It moves back and forth with the swing of the rotating rod 11 to remove dust from the surface of the filter plate 5.
[0036] Working principle: After prolonged use, the laser head 4 will be damaged and needs replacement. Pulling the data cable 2 outwards moves the connecting ring 21 outwards. The connecting ring 21, through the ball 22, moves the locking ring 24, causing the ball 22 to disengage from the locking ring 20. The ball 22 moves into the locking ring 24, and the connecting ring 21 disengages the data cable 2, thus completing the replacement. After replacement, pushing the data cable 2 moves the connecting ring 21, which then engages with the locking ring 24 through the ball 22. Dust will be generated during laser use. Starting the motor 7 will rotate the disc 8, which in turn rotates the limiting post 9, restricting... The column 9 drives the rotating rod 11 to swing. The swing of the rotating rod 11 drives the scraper 6 to move back and forth through the sliding column 12 to clean the surface of the filter plate 5. When the internal structure is damaged and needs to be replaced, press down the pressing block 18. The pressing block 18 drives the locking block 16 to press down, so that the head of the locking block 16 disengages from the locking block 19, thereby removing the filter plate 5 and replacing the internal structure of the box 1. After the replacement is completed, the connecting block 19 is locked into the locking block 16. The spring 14 drives the fixing column 15 to generate elastic potential energy, which squeezes the connecting block 19, making the connecting block 19 more securely locked and fixing the filter plate 5 more firmly to the box 1.
[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
