“…The Z -scan measurement results confirm that Ti 3 C 2 T x and Ta 4 C 3 T x SAs possess fascinating saturable absorption behaviors at the 1 μm spectral region, which can be ascribed to the plasmon-enhanced ground state absorption . In particular, relatively low saturable intensity and high modulation depth in contrast to graphene-based SAs are favorable parameters of an SA element with a view to deliver laser pulses with ultrashort pulse durations and high repetition frequencies. − The imperfect fitting results may be attributed to the uneven distribution of MXene samples on the substrate surface, which can be improved by selecting better LPE and spin-coating parameters.…”

Two-dimensional (2D) carbides of transition metals, so called "MXenes", maintain excellent optical properties and unique layer stacking form via hydrogen bonds in contrast to other low-dimensional materials. These promising features have attracted increasingly research interest in the field of ultrafast photonics. In this work, titanium carbide (Ti 3 C 2 T x ) and tantalum carbide (Ta 4 C 3 T x ), as two promising MXene materials for photonic applications, are experimentally synthesized by the ultrasound-assisted liquid phase exfoliation technique. The morphology of prepared few-layer Ti 3 C 2 T x and Ta 4 C 3 T x has been systematically characterized by transmission electron microscopy and X-ray diffraction analysis. Density functional theory is performed to obtain their electronic band structures, demonstrating metallic properties and verifying their optical absorption at 1 μm. Their tempting optical modulation properties for multi-gigahertz pulsed laser emission are demonstrated by using them as saturable absorbers in a waveguide laser cavity. Particularly, high-performance Q-switched mode-locked lasers with/without laser mirrors are realized based on the hybrid waveguide laser configuration, delivering 1 μm laser pulses with durations as short as 30 ps. The results presented in this work show the great potential of metallic MXenes and waveguide structures for applications in functional photonic devices.

“…However, such two-dimensional materials also face many problems and have limitations in range of their applications. For example, graphene has a particularly low optical absorption and a small modulation depth [6][7]. The transition metal sulfide represented by MoS2, which has a large band gap and a short working band, is mostly applied in the visible-light range [8][9].…”

In this paper, we propose a novel ultrafast laser with nanostructure CH3NH3PbI3 nanorods, yielding a higher modulation depth and lower optical loss. Our experiment is performed through nanopatterned CH3NH3PbI3 rods and an allsolid-state passive mode-locked laser system. The prepared nanoarray CH3NH3PbI3 perovskite exhibits a modulation depth of 8.1% under a saturation intensity of 9.53 MW/cm 2 . By applying the CH3NH3PbI3 nanoarray as a saturable absorber in the ultrafast 1064-nm laser system, a mode-locked pulse with a 30-ps pulse width and an 87.3-MHz repetition rate is achieved. A maximum output power of 542 mW was measured, under an absorption pump power of 5.4 W. With the new structured CH3NH3PbI3, our experiment verifies a new method in ultrafast lasers with low light loss, which potentially uncovers an avenue to develop ultrafast lasers.

“…To date, there are a large number of works devoted to the study of the nonlinear optical properties of carbon nanotubes, graphene, and various composites based on them. These works are aimed at investigating, e.g., optical limiting (a nonlinear decrease of the transmitted light intensity) [1] and saturable absorption (a nonlinear increase of the transmitted light intensity) [2] to develop and create optical limiters of nanosecond laser pulses [3][4][5][6][7][8][9][10][11][12][13] and passive laser shutters for generating picosecond and femtosecond laser pulses [14][15][16][17][18][19][20][21][22][23][24], respectively. Nanodiamond, being another form of nanocarbon material, is also attractive due to its unique properties [25][26][27][28][29][30][31][32][33].…”

Femtosecond Optical Nonlinearity of Nanodiamond Suspensions

et al. 2021

High pressure-high temperature (HP-HT) nanodiamonds and detonation nanodiamonds have unique optical properties and are promising materials for various applications in photonics. In this work, for the first time, comparative studies of the nonlinear optical properties of aqueous suspensions of HP-HT and detonation nanodiamonds under femtosecond laser excitation are performed. Using the z-scan technique, it was found that for the same laser pulse parameters HP-HT nanodiamonds exhibited optical limiting due to two-photon absorption while detonation nanodiamonds exhibited saturable absorption accompanied by short-term optical bleaching, revealing the different electronic-gap structures of the two types of nanodiamonds. The saturable absorption properties of detonation nanodiamonds are characterized by determining the saturable and non-saturable absorption coefficients, the saturation intensity, and the ratio of saturable to non-saturable losses. The nonlinear absorption in HP-HT nanodiamonds is described with the nonlinear absorption coefficient that decreases with decreasing concentration of nanoparticles linearly. The results obtained show the possibility of using aqueous suspensions of nanodiamonds for saturable absorption and optical limiting applications.
