Description

Technical Field

[0001] This invention belongs to the field of radio frequency lasers, and in particular relates to a radio frequency laser capable of bidirectional light output with equal power. Background Technology

[0002] With the widespread application of laser technology in industrial processing, scientific research, and optical communication, the performance requirements for laser output beams are increasing. In some applications requiring bidirectional beams, such as double-sided laser welding, laser surface treatment of symmetrical structures, and optical communication systems based on bidirectional optical transmission, it is not only required that the laser achieve bidirectional light output, but it is also desirable that the laser power output in both directions remains equal to ensure the consistency of processing results or the stability of communication signals.

[0003] Existing technologies struggle to achieve equal power output in both directions, and the output spot size cannot be adjusted. In schemes using beam splitters to achieve bidirectional laser output, the splitting ratio is difficult to make absolutely uniform, and the performance of the beam splitter changes after prolonged operation, further exacerbating power unevenness. Schemes using multiple laser cavities for bidirectional output also fail to guarantee equal power output due to performance differences between cavities and the difficulty of control. This bidirectional laser power unevenness severely impacts the application effect and working quality of lasers in related fields, limiting their further development and widespread adoption.

[0004] Therefore, there is an urgent need for a radio frequency laser that can achieve bidirectional stable light output, equal laser power in both directions, and convenient adjustment of the output spot size. Utility Model Content

[0037] See Figure 1-4 This invention provides a radio frequency laser capable of bidirectional and equal power output. The laser includes a metal housing 1, an upper housing, an optical path tube 2, a positive electrode plate, a negative electrode plate, two reflector assemblies, a radio frequency power supply 6, and a power adjustment structure. The upper housing is positioned above the metal housing 1, and a laser resonant cavity is located within the metal housing 1. The optical path tube 2, the positive electrode plate, and the negative electrode plate are all detachably mounted within the laser resonant cavity, with the optical path tube 2 located between the positive and negative electrode plates. The reflector assembly includes a mounting component 3, a total reflection mirror 4, and an output mirror 5. The total reflection mirror 4 and the output mirror 5 are spaced apart on the mounting component 3, and the mounting components 3 of the two reflector assemblies are detachably mounted at both ends of the metal housing 1. The radio frequency power supply 6 is located within the upper housing and supplies power to the laser gain medium within the optical path tube 2. The power adjustment structure is located within the upper housing and adjusts the power of the laser output from the two output mirrors 5 to ensure that the laser power output from both sides remains equal.

[0038] In this radio frequency laser capable of bidirectional and equal power output, a metal casing 1 serves as the outer shell of the laser, providing mechanical support and electromagnetic shielding. Inside, a laser resonant cavity is formed, and an optical path tube 2 is located within this cavity. The optical path tube 2 constrains the laser propagation path within the cavity, ensuring laser mode stability. An radio frequency power supply 6 acts as the pump source, providing a stable radio frequency excitation signal to excite the laser gain medium and generate laser light. Under the excitation of the radio frequency power supply 6, the laser gain medium within the optical path tube 2 generates laser light, which propagates within it. Two total reflection mirrors 4 are located on either side of the metal casing 1, staggered vertically. Two output mirrors 5 are also located on either side of the metal casing 1, staggered vertically. The total reflection mirrors 4 highly reflect the laser light, causing multiple reflections within the optical path tube 2 to enhance energy. The output mirrors 5 allow partial laser light transmission for output. Under the combined action of the total reflection mirrors 4 and the output mirrors 5, a stable laser beam is formed through reciprocating oscillations. The laser light exits from the output mirrors 5 on either side of the metal casing 1, achieving bidirectional output. Furthermore, the power adjustment structure adjusts the operating parameters according to the control signal to modulate the laser, change the laser energy loss, and achieve dynamic adjustment of bidirectional output power until the power is equal. This ensures equal output laser power in both directions, meeting the requirements of applications with high power consistency requirements and improving the application performance and applicability of the laser. In addition, the optical path tube 2, positive electrode plate, and negative electrode plate are detachably mounted in the laser resonant cavity. The installation and removal of the optical path tube 2 from the metal housing 1 are convenient. The output spot size can also be adjusted by replacing the optical path tube 2 with different diameters to adapt to different application scenarios. The mounting component 3, which houses the total reflection mirror 4 and the output mirror 5, is detachably connected to the metal housing 1, facilitating the replacement of the total reflection mirror 4 and the output mirror 5 with different lens parameters or sizes.

[0039] In this embodiment, the power adjustment structure is a modulator. The modulator controls the power energy of the light emitted from both sides through the control signal inside the RF power supply 6, thereby dynamically adjusting the power of the bidirectional laser and ultimately achieving equal power output from both sides. The specific structure, connection method, and control method of the modulator are prior art and will not be described in detail here.

[0040] In this embodiment, both the positive and negative electrode plates are connected to the optical path tube 2 via ceramic limiting posts, and both are connected to the metal casing 1 via spring-loaded structures. The spring-loaded structures allow the positive and negative electrode plates to be detachably mounted on the inner wall of the metal casing 1. Specifically, the spring-loaded structure includes a metal spring and a limiting structure. When the positive or negative electrode plate presses against the metal spring, the limiting structure fixes the relative position of the positive or negative electrode plate to the metal casing 1. The optical path tube 2 is connected to the positive and negative electrode plates via the ceramic limiting posts. When replacing the optical path tube 2 with one of different diameters, the optical path tube 2, the positive electrode plate, and the negative electrode plate must be removed or installed together.

[0041] In this embodiment, the mounting workpiece 3 is connected to the metal shell 1 by a clamp, which facilitates installation and disassembly. The specific structure of the clamp is prior art and will not be described further here.

[0042] In this embodiment, a first sealing structure is provided between the mounting workpiece 3 and the metal shell 1. The first sealing structure can seal the gap between the mounting workpiece 3 and the metal shell 1, ensuring the sealing of the laser resonant cavity.

[0043] In this embodiment, a second sealing structure is provided between the total reflection mirror 4 and the mounting workpiece 3, and a third sealing structure is provided between the output mirror 5 and the mounting workpiece 3. The second sealing structure can seal the gap between the total reflection mirror 4 and the mounting workpiece 3, and the third sealing structure can seal the gap between the output mirror 5 and the mounting workpiece 3, ensuring the sealing of the laser resonant cavity. In this embodiment, the bidirectional and equally powered radio frequency laser also includes a heat dissipation structure 7, which is disposed below the metal casing 1. The heat dissipation structure 7 is used to cool the radio frequency laser.

[0044] In this embodiment, the upper housing is provided with a power connection port 8. In practical applications, it can be connected to an RF power supply cable via the power connection port 8 to ensure stable power input.

[0045] In this embodiment, the upper housing is provided with a control signal port 9. In practical applications, devices that need to be connected to the power regulation structure are connected to the power regulation structure through the control signal port 9.

[0046] In this embodiment, the optical path tube 2 is N-shaped. Two total reflection mirrors 4 are located at the two inflection points of the N-shaped optical path tube 2, and two light exiting mirrors 5 are located at the two free ends of the N-shaped optical path tube 2.

[0047] Regularly check the connections of all components of the RF laser to ensure they are secure; tighten any loose connections immediately. Inspect optical path tube 2 for damage or contamination; replace or clean it promptly if necessary. Regularly test the output power and stability of the RF power supply 6 to ensure its normal operation. Simultaneously, maintain a clean and dry working environment for the laser to prevent dust and moisture from affecting its performance.
