Embodiment 1

[0051] Please refer to figure 1 , figure 1 The saturable absorber based on MXene two-dimensional material provided for an embodiment of the present invention includes an optical waveguide and an MXene two-dimensional material 12 arranged on the optical waveguide, and the MXene two-dimensional material 12 is used to modulate the light beam transmitted in the optical waveguide, Realize the self-starting of the laser. MXene two-dimensional material 12 is a new type of two-dimensional material. The MXene two-dimensional material 12 in the present invention has high damage threshold, high modulation depth, excellent oxidation resistance, and remains stable in air for a long time. The obtained saturable absorber It has good stability and can be used for passive mode locking for a long time. It is currently an ideal type of saturable absorber. The hybrid mode-locked device composed of MXene two-dimensional material 12 and nonlinear polarization rotation device is an effective way t...

Embodiment 2

[0057] The only difference between embodiment 2 and embodiment 1 is: as figure 2 As shown, the optical waveguide is a tapered fiber 21, and the MXene two-dimensional material 22 is coated on the outer surface of the tapered fiber 21. The two-dimensional MXene material 22 is used to modulate the beam transmitted in the tapered fiber 21 to realize the self-starting of the laser.

Embodiment 3

[0059] Embodiment 3 differs from Embodiment 1 only in that: as image 3 As shown, the optical waveguide is a plane mirror 31, and the MXene two-dimensional material 32 is attached to the reflection surface of the plane mirror 31. The MXene two-dimensional material 32 is used to modulate the beam reflected by the plane mirror 31 to realize the self-starting of the laser. During modulation, the beam is reflected by the plane mirror 31, and the beam modulation process is realized when the beam passes through the MXene two-dimensional material 32.
