Sb2Te3 topological insulator for 52 nm wideband tunable Yb-doped passively Q-switched fiber laser

Quasi-2D Mn3Si2Te6 Nanosheet for Ultrafast Photonics

“…The core position is completely covered by Mn 3 Si 2 Te 6 nanosheets and has been marked by red circles. The optical source of the two-arm detection system [ 48 ] is a pulsed laser with an operating wavelength of 1550 nm, a repetition frequency of 16.6 MHz, and a pulse duration of 448 fs.…”

Mode-locking pulse generation based on lead-free halide perovskite CsCu2I3 micro-rods with high stability

“…[1][2][3][4] A saturable absorber (SA) is an important optical component to trigger pulsed operation. 5 Recently, the application of SAs based on novel low-dimensional materials for ultrafast pulse generation has been widely reported, such as graphene, [6][7][8] carbon nanotubes (CNTs), [9][10][11] topological insulators (TIs), [12][13][14][15] transition metal dichalcogenides (TMDs), [16][17][18][19] black phosphorus (BP), 20 and so on. [21][22][23][24][25] Most of them have unique optical and electrical properties.…”

Synthesis of Hexagonal Structured GaS Nanosheets for Robust Femtosecond Pulse Generation

“…Furthermore, the properties of material-based SA such as the linear loss, the modulation depth, and the working wavelength can also be optimized in the fabrication process [19]. To date, graphene [20,21], topological insulator (TI) [22][23][24], transition metal dichalcogenides (TMDCs) [25][26][27], Mxene [28,29], bismuthine [30][31][32], and black phosphorus (BP) [33] have been applied in ultrafast fiber lasers [34][35][36][37]. Previous studies mostly focus on how the pulse width can be greatly compressed, for example, adding positive dispersion fiber for dispersion management [38,39].…”
