A mode-locked laser system comprises a stimulating laser pump, a pulse-modulating laser pump, and an optical oscillator. The stimulating laser pump and the pulse-modulating laser pump emit a stimulating laser light and a pulse-modulating laser light. The optical oscillator further includes a gain medium, a saturable absorber, a first terminal, and a second terminal. The stimulating laser light and the pulse-modulating laser light are emitted into the gain medium to generate a gain laser light. When the gain laser light is emitted into the saturable absorber, an ultra-short pulse laser light is generated. |
