Development of High Stability Pump Source System for Fiber Lasers
To improve the output performance of semiconductor lasers,a highly stable laser pump source system was designed.The system includes a laser pump module and a peripheral control system.The test results of the pump source system show that there is a good linear relationship between the output power and the driving current,the short-term stability of the output optical power is 0.061 3%,the long-term stability is 0.108 0%,and the central wavelength of the output spectrum is stable over a long period of continuous operation.When it was applied to a fiber laser,the central wavelength of the output laser pulse spectrum was shifted by only 4 pm in a continuous test.
