Embodiment Construction
[0030] Attached below Figure 1 to Figure 3 A detailed description of the specific implementation of the system:
[0031] For the wavelength tunable random laser system of the present invention, refer to the system diagram Figure 1 to Figure 3 , Including first pump source 1, first seed source 2, second seed source group 3, first WDM4, second WDM5, third WDM6, coupler 7, optical fiber 8, fourth WDM9, first reflector 10 , The second reflector 11, the fifth WDM 12, the additional seed source group 13.
[0032] in figure 1 In, the first pump source 1 is connected to the first WDM4 through an optical fiber, the first WDM4 and the first seed source 2 are connected to the second WDM5 together, and the second WDM5 and the second seed source group 3 are connected to the third WDM6 together, The third WDM 6 is connected to the coupler 7, and the coupler 7 is connected to the optical fiber 8. The first pump source 1 of the high-power wavelength tunable laser and the first seed source 2 and...
