Embodiment 1
[0020] Embodiment 1: Concrete structure of the present invention
[0021] The active-passive hybrid mode-locked fiber laser pulse generation system structure of the present invention is as attached figure 1 As shown, its structure is that the pump light source 1 (980nm laser, the maximum output power is 1W) is connected to the 980nm end of the wavelength division multiplexer 2 (980 / 1550nm wavelength division multiplexer), and the wavelength division multiplexer 2 The 1550nm end is connected to the input end of the first optical coupler 3 (1×2 standard single-mode optical coupler, with a splitting ratio of 10:90); the 10% output end of the first optical coupler 3 is connected to the polarization controller 4 (three One end of the ring-type mechanical fiber polarization controller) is connected, and the optical pulse output by it continues to run in the resonator of the active mode-locked fiber laser, and 90% of the output end of the first optical coupler 3 is connected to the ...
Embodiment 2
[0023] Embodiment 2 Working process of the present invention and the effect of each main component
[0024] attached figure 1 In the structure shown, the pumping light source 1 is used as the laser pumping source of the whole system, and the pumping light source 1 enters the system through the wavelength division multiplexer 2; the first optical coupler 3 with a splitting ratio of 10:90 connects The running laser is divided into two parts, one part (90%) is output to the third optical coupler 11, and the other part (10%) continues to run in the resonator of the active mode-locked fiber laser; the third light splitting ratio is 40:60 The coupler 11 divides the laser light output by the first optical coupler 3 into two parts, one part (60%) is used as the laser output of the whole system, and the other part (40%) is output to the fourth optical coupler 12 as a feedback signal of the system; The polarization controller 4 is used to control the polarization state in the system; th...
