| titleOfInvention | Laser-induced graphene electrically tunable passively mode-locked fiber laser |
| abstract | The invention discloses an electrically tuned passive mode-locking fiber laser based on laser-induced graphene, which belongs to the technical field of mode-locking fiber lasers. The laser includes: semiconductor pump source, wavelength division multiplexer, erbium-doped gain fiber, Co2+:ZnS saturable absorber, polarization controller, optical isolator, optical coupler, laser-induced graphene electrical tuning device, DC power supply . The laser-induced graphene electrical tuning device consists of a laser-induced graphene electrode and a long-period fiber grating. Using the saturable absorber properties of Co2+:ZnS material, the laser can achieve stable mode locking, and at the same time, the electrical energy of the DC power supply is converted into heat energy through the graphene electrode. The temperature change of the graphene electrode will cause the transmission spectrum of the long period grating to change, and then The output wavelength tuning of the mode-locked laser is realized. The wavelength-tunable mode-locking laser has the advantages of simple preparation, low cost, fast tuning speed, high tuning accuracy, convenient use, all-optical structure, etc., and is easy to be applied in industrialization. |
