Semiconductor laser side pumping module based on power feedback control

Номер: CN116387968A
Автор: QI BAOHUA
Принадлежит:

The invention provides a semiconductor laser side pumping module based on power feedback control, which comprises a semiconductor laser array, a module optical element, a state monitoring module, a current adjusting module and a data storage processing communication module, and adopts multi-wavelength combined pumping, so that the pumping light spectrum is wider than the absorption peak of a laser crystal; when the semiconductor laser array is degraded, the semiconductor laser array can be well matched with the absorption peak of the laser crystal, fluorescence intensity monitoring is adopted, and the current of the semiconductor laser array is dynamically adjusted according to the monitoring intensity and other module state monitoring data, so that the fluorescence intensity is kept stable when the conversion efficiency of the semiconductor laser array is reduced, and meanwhile, the detection accuracy is improved. And storing various state monitoring data of the semiconductor laser pumping ...
