Method, device and equipment for adjusting output power of fiber laser, and medium

The invention discloses an output power adjusting method, device and equipment of an optical fiber laser and a medium, and belongs to the field of industrial machining.The method comprises the steps that the internal temperature is obtained, the monitoring position of a temperature sensor is selected for reflecting the real internal situation, and the internal temperature is in positive correlation with the temperature of the environment where the optical fiber laser is located; if the internal temperature is within the preset safe temperature range, acquiring the output power of the fiber laser; if the output power is not equal to the required power, obtaining the current in the pump; and based on a preset power increase and decrease coefficient, controlling the current to adjust the output power until the output power is equal to the required power. In the application, the internal temperature and the output power are judgment conditions for power adjustment, the output power is adjusted after the condition
