Research Progress On Passively Q-Switched Lasers Based On New Saturable Absorption Devices

Passively Q-switched technology, as an important branch of Q-switchcd technology, has gained important applications in laser technology fields. Using new saturable absorption devices to achieve passively Q-switched process is a research hotspot currently. In this paper, the properties and advantages of graphene, MXene, and gold nanomaterials arc briefly introduced, and the research progress of using these materials as saturable absorbers in passively Q-switched lasers is summarized. The combination of new materials and passively Q-switched technology provides a reference for further researches on passively Q-switched technology and promotes the application of new materials in passively Q-switched lasers.
