A highly efficient graphene oxide absorber for<i>Q</i>-switched Nd:GdVO<sub>4</sub>lasers

Abstract. We have demonstrated the dissipative solitons generated in an ytterbium-doped fiber laser cavity using graphene oxide as the saturable absorber. The lasing light, centered at 1077.2 nm, has a 3 dB spectral bandwidth of ∼1.12 nm. Under different launched pump powers and appropriate polarization orientations, harmonic mode-locked of second-and third-order pulse trains have been achieved; the corresponding 3-dB bandwidth and pulse duration have been detected. © The Authors.

A novel black phosphorus (BP) solution saturable absorber (SA) is fabricated by the liquid-phase-exfoliated method and successfully used for passively Q-switched (QS) Nd:YVO 4 laser. Compared with a traditional solid SA, a BP solution SA possesses more excellent optical transparency and higher damage resistance. The shortest pulse duration and highest average output power are measured to be 119 ns and 1.23 W, respectively. To the best of our knowledge, both of them are the best results among QS solid-state lasers with BP-based absorbers so far. High power Q-switched (QS) laser pulses of nanosecond time duration always have extensive applications in the fields of material processing, biomedicine, spectroscopy, and so on. Therefore, the manufacture of QS solid-state lasers (SSLs) with high output power and narrow pulse width is extremely essential. As a significant technique for generating nanosecond laser pulses, passively Q-switching in SSLs depends absolutely on high-quality saturable absorbers (SAs) [1,2] . Since 2009, due to the intrinsic zero bandgap and large nonlinear absorption wavelength range [3][4][5] , Graphene has been extensively applied to the pulse generation of various wave bands [3][4][5][6][7] . The successful applications of graphene inspire researchers to explore other graphene-like two-dimensional (2D) materials such as topological isolators (TIs) [8,9] and transition metal dichalcogenides (TMDs) [10,11] . Over the last few years, these emerging 2D materials have experienced a rapid development. Many kinds of SAs fabricated with 2D materials are used for mode locking or Q-switching technology in different lasers [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22] . Recently, as another kind of 2D nanomaterial, black phosphorus (BP) has attracted significant attention in the field of nonlinear optical materials. Compared with other allotropes of phosphorus, BP possesses a "wrinkled" layered structure and a relatively strong thermodynamic stability [23,24] . In addition, BP is a highmobility semiconductor with a direct bandgap sensitivity depending on the number of layers from 0.3 (bulk) to 2.0 eV (single layer) that exactly fill the gap between the zero bandgap of graphene and the wide bandgap (1.0-2.0 eV) of TMDs [25] . The narrower bandgap of BP makes itself act as the SA, which has been used in a broader wavelength operation range of 4-0.8 μm [26,27] . In addition, like graphene, BP SA owns the same excellent nonlinear optical response and easy fabrication process [13,23] . Q-switching or mode locking in SSLs using graphenelike absorbers [9,15,16,18,20,21,26,27,[29][30][31][32][33][34][35] are listed in Table 1. These absorbers are made by growing nanomaterials by chemical vapor deposition and transferring themon a mirror or depositing them on the quartz substrate by the spin-coating method. However, even if the reports are numerous, the average output power of the pulsed lasers is very limited. The maximum average output power reported is only 820 mW [33] (Q-switching) [29] (...
