Description

Technical Field

[0001] This utility model relates to the field of anti-displacement bracket technology, specifically an anti-displacement bracket for a narrow linewidth laser optical cavity. Background Technology

[0002] Narrow-linewidth lasers are a type of special laser characterized by ultra-narrow spectral linewidths. Their core feature is a highly concentrated spectral distribution of the output laser, with energy distribution existing only within an extremely narrow range around the center frequency. This characteristic makes them irreplaceable in fields such as precision measurement, communication, and quantum technology.

[0003] Traditional narrow-linewidth lasers have significant shortcomings in anti-offset capability, and their output frequency is easily affected by environmental disturbances, thus affecting the operation of narrow-linewidth lasers. To address this, we propose an anti-offset bracket for the optical cavity of narrow-linewidth lasers. Utility Model Content

[0004] The purpose of this invention is to provide an anti-displacement bracket for the optical cavity of a narrow linewidth laser, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An anti-displacement bracket for the optical cavity of a narrow linewidth laser includes a support plate, a rolling groove, a lead screw, a slider, a movable plate, a vertical plate, a narrow linewidth laser body, and a sliding groove. The top of the support plate has a rolling groove, and the lead screw is rotatably connected inside the rolling groove. The outer surface of the lead screw is threadedly connected to a slider. The top of the slider is fixedly mounted on a movable plate. Vertical plates are fixedly mounted on both sides of the top of the movable plate. The top of the vertical plate is fixedly mounted on the narrow linewidth laser body. A sliding groove is opened on one side of the support plate, and an extension plate is fixedly mounted on the bottom of the movable plate.

[0007] A locking block is fixedly installed on one side of the extension plate, and the locking block is slidably connected to the inside of the slide groove.

[0008] A servo motor is fixedly installed inside the rolling groove, and the output end of the servo motor is fixedly connected to the lead screw.

[0009] The support plate has several push rods fixedly installed at its bottom, and electric push rods are movably installed at the bottom of the push rods. The electric push rods are fixedly installed at their bottoms.

[0010] The base has a rotating platform fixedly installed at its bottom, and the rotating platform has a fixed platform at its bottom.

[0011] The top of the fixed platform is fixedly equipped with a rotary motor, and the bottom of the rotary platform is provided with a fixing groove.

[0012] The output end of the rotary motor is fixedly connected to the fixed groove, and a number of balls are rolledly connected to the top of the fixed platform, with the balls in contact with the bottom of the rotary platform.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. A misalignment prevention bracket for the optical cavity of a narrow-linewidth laser is disclosed. This bracket uses a servo motor to drive a lead screw to rotate, thereby adjusting the horizontal position of the narrow-linewidth laser body. The servo motor is fixed inside a rolling groove, and its output end is rigidly connected to the lead screw. When the motor starts, the lead screw rotates stably within the rolling groove, driving a slider with a threaded connection on its outer surface to move linearly along the groove. A movable plate at the top of the slider moves synchronously with the slider, while an extension plate at the bottom of the movable plate slides into a groove on a support plate via a locking block on one side. The locking block's limiting effect within the groove effectively restricts the lateral misalignment of the movable plate, ensuring that the laser body moves smoothly along a preset trajectory during horizontal adjustment, preventing optical path misalignment due to shaking. The rigid fixation of the laser body by the upright plate further enhances the stability of the overall structure, providing a fundamental guarantee for the precise alignment of the optical cavity.

[0015] 2. This invention relates to an anti-displacement bracket for a narrow-linewidth laser optical cavity. The bracket features flexible height and angle adjustment capabilities to adapt to different working scenarios. A push rod at the bottom of the support plate is movably connected to an electric push rod. When the electric push rod extends or retracts, it drives the entire support plate to rise or fall, achieving height adjustment of the laser body and meeting the coupling height requirements of different optical systems. Angle adjustment is achieved by a rotary motor driving a rotating platform and a fixed platform at the bottom of the base. The output end of the rotary motor is connected to a fixed groove at the bottom of the rotating platform. When the motor is started, the rotating platform rotates around the center of the fixed platform, while the ball bearings on the top of the fixed platform contact the bottom of the rotating platform, converting sliding friction into rolling friction, reducing rotational resistance and improving the smoothness of angle adjustment. The overall structure, through the rigid support of the base and fixed platform, combined with the precise cooperation of various adjustment components, ensures the stability of the laser optical cavity while achieving multi-dimensional adjustment, preventing external vibrations or interference with the optical path during the adjustment process.

[0021] 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.

[0022] Please see Figure 1 - Figure 4 As shown, this utility model provides a technical solution:

[0023] An anti-displacement bracket for the optical cavity of a narrow linewidth laser includes a support plate 1, a rolling groove 2, a lead screw 3, a slider 4, a movable plate 5, a vertical plate 6, a narrow linewidth laser body 7, and a sliding groove 8. The top of the support plate 1 has a rolling groove 2, and the lead screw 3 is rotatably connected inside the rolling groove 2. The slider 4 is threadedly connected to the outer surface of the lead screw 3. The top of the slider 4 is fixedly mounted on the movable plate 5. The two sides of the top of the movable plate 5 are fixedly mounted on the vertical plate 6. The top of the vertical plate 6 is fixedly mounted on the narrow linewidth laser body 7. The sliding groove 8 is opened on one side of the support plate 1. The bottom of the movable plate 5 is fixedly mounted on an extension plate 9.

[0024] A locking block 10 is fixedly installed on one side of the extension plate 9. The locking block 10 is slidably connected to the slide groove 8. A servo motor 11 is fixedly installed inside the rolling groove 2. The output end of the servo motor 11 is fixedly connected to the lead screw 3. Several push rods 13 are fixedly installed at the bottom of the support plate 1. An electric push rod 12 is movably installed at the bottom of the push rods 13. A base 14 is fixedly installed at the bottom of the electric push rod 12. A rotating table 15 is fixedly installed at the bottom of the base 14. A fixed platform 16 is installed at the bottom of the rotating table 15. A rotary motor 17 is fixedly installed at the top of the fixed platform 16. A fixed groove 18 is opened at the bottom of the rotating table 15. The output end of the rotary motor 17 is fixedly connected to the fixed groove 18. Several balls 19 are slidably connected to the top of the fixed platform 16. The balls 19 are in contact with the bottom of the rotating table 15.

[0025] Servo motor 11 is a small, high-precision servo motor equipped with an encoder for closed-loop position control. The motor housing is bolted to the pre-reserved mounting base at the end of the rolling groove 2. The output shaft and lead screw 3 are rigidly connected via a coupling. The coupling is of the elastic type to compensate for minor installation deviations. Push rod 13 is a solid steel rod, welded to the bottom of support plate 1 at the top and inserted into the telescopic end of electric push rod 12 at the bottom, with a clearance fit. Electric push rod 12 is an industrial-grade DC electric push rod, fixedly connected to base 14 at the bottom, and features a self-locking function, maintaining high stability after power failure. Rotary motor 17 is a servo motor 11 with a gearbox. The motor is bolted to the mounting cavity at the bottom of fixed platform 16, and its output shaft is connected to the fixed slot 18 of rotary table 15, enabling precise angle adjustment of rotary table 15.

[0026] In this embodiment, an anti-offset bracket for a narrow-linewidth laser optical cavity is used. First, the bracket drives a lead screw 3 to rotate via a servo motor 11 to adjust the horizontal position of the narrow-linewidth laser body 7. The servo motor 11 is fixed inside the rolling groove 2, and its output end is rigidly connected to the lead screw 3. When the motor starts, the lead screw 3 rotates stably within the rolling groove 2, driving the slider 4, which is threaded on its outer surface, to move linearly along the groove. The moving plate 5 at the top of the slider 4 moves synchronously with the slider 4, while the extension plate 9 at the bottom of the moving plate 5 forms a sliding engagement with the slide groove 8 of the support plate 1 via a locking block 10 on one side. The limiting effect of the locking block 10 within the slide groove 8 effectively restricts the lateral offset of the moving plate 5, ensuring that the laser body always moves smoothly along a preset trajectory during horizontal adjustment, avoiding optical cavity optical path offset due to shaking. The rigid fixation of the laser body by the upright plate 6 further enhances the stability of the overall structure, providing a basic guarantee for the precise alignment of the optical cavity. Then, the bracket has flexible adjustment capabilities in height and angle to adapt to different working scenario requirements. The push rod 13 at the bottom of the support plate 1 is movably connected to the electric push rod 12. When the electric push rod 12 extends or retracts, the push rod 13 drives the support plate 1 to rise and fall as a whole, realizing the height adjustment of the laser body and meeting the coupling height requirements of different optical systems. The rotating stage 15 and the fixed stage 16 at the bottom of the base 14 are driven by a rotary motor 17 to achieve angle adjustment. The output end of the rotary motor 17 is connected to the fixed groove 18 at the bottom of the rotating stage 15. When the motor is started, the rotating stage 15 rotates around the center of the fixed stage 16. At the same time, the ball bearing 19 on the top of the fixed stage 16 contacts the bottom of the rotating stage 15, converting sliding friction into rolling friction, reducing rotational resistance and improving the smoothness of angle adjustment. The overall structure, through the rigid support of the base 14 and the fixed stage 16, combined with the precise cooperation of each adjustment component, ensures the stability of the laser optical cavity while realizing multi-dimensional adjustment, avoiding interference to the optical path caused by external vibration or adjustment process.
