[0038] The red light in the fiber laser can be used as a positioning marker to help the user determine the position and direction of the laser emission. This is particularly important in applications that require precise positioning, such as laser cutting, laser marking, and other industrial applications. The high visibility of the red light allows the user to clearly see the path of the laser beam, ensuring the accuracy and safety of the operation. Red light can also be used for performance testing and debugging of fiber lasers. By detecting the intensity and wavelength of the red light, key performance indicators such as power, wavelength stability, and beam quality of the laser can be evaluated. During the debugging process, the red light serves as a reference light, allowing for easy adjustment of the various indicators of the laser to achieve optimal working conditions. The red light tooling ensures that the red light tube can accurately and stably emit at the rated current and integrate with the fiber laser. Through the stable output of red light, the loss of each device and fusion point in the optical path and the fiber fusion effect can be calculated in advance to intercept defective products.

[0039] At present, the red light tool powered by the fiber laser for the red light tube is difficult to guarantee the stability of power supply, first, the voltage fluctuation can cause the red light tube to emit light unstable or even damage the red light tube, second, the tool needs to design accurate current control circuit, if the current is too large or too small, it will cause unstable light emission or damage.
