“…Q-switched erbium-doped fiber lasers (EDFLs) have received extensive attentions as an important tool for the applications of optical communication, remote sensing, and laser therapy [1][2][3][4]. Compared with the active Q-switching, passive Q-switching possesses the advantages of compactness and flexibility in design [5][6][7]. A saturable absorber (SA) is an essential device for passive Q-switching [8][9][10].…”

Chromium carbide (Cr3C2), as a kind of transition metal carbides, has exhibited extraordinary optoelectronic properties and aroused enormous attention. However, few reports have been focused on the nonlinear properties and relevant devices. In this study, we first demonstrated a novel Cr3C2 saturable absorber (SA). Cr3C2 with an average size of 200 nm was prepared through a low temperature salt flux synthetic method. The Cr3C2-film SA exhibited high robustness and strong linear and nonlinear saturable absorption response at 1560 nm. As the Cr3C2 SA was inserted into the Er3+-doped fiber laser cavity, Q-switched pulses were generated with a central wavelength of 1560 nm. To the best of our knowledge, this was the first report on the optical nonlinearity of Cr3C2 as a Q-switcher for the near-infrared fiber laser. Our experimental results verified that the integrated Cr3C2-based device possessed great potential as a nonlinear optical medium for high-performance optical applications.

“…The Q-switching operation can be produced in a laser by inserting a saturable absorber (SA) material into its cavity [ 6 , 7 ]. Several SA materials have been used to effectively produce laser pulses that are Q-switched [ [8] , [9] , [10] , [11] ]. Among these materials, transition metal dichalcogenides (TMDs) are relatively easy to exfoliate and possess high nonlinear optical response [ 12 ].…”
