and a large two photon absorption (TPA) coefficient ((−6.98 ± 0.6) × 103 cm GW−1 21). However, BP lacks sufficient air stability, resulting in the rapid degradation of its NLO properties. Meanwhile, the most studied TMDC materials (MX2, M = Mo, W, and X...
When fabricating large array of periodic Si nanodisks, self-organized PS spheres assembling in a hexagonally close-packing manner were prepared as the monolayer mask. The as-prepared Si samples are pre-annealed to switch into crystalline phase, before performing all the nonlinear scattering ...

ing process, where the absorption of two photons (ħω) at the excitation wavelength assisted by a first plasmonic mode, results in a radiative frequency-doubled photon (2ħω) assisted by a second plasmonic mode, restoring the system ground state through the emission of a SH photon [18]...
MoS2Strong two-photon absorption (TPA) in monolayer MoS2 is demonstrated in contrast to saturable absorption (SA) in multilayer MoS2 under the excitation of femtosecond laser pulses in the near infrared region. MoS2 in the forms of monolayer single crystal and multilayer triangular islands are grown...
in the ground state. When\(\omega = \bar \omega _{2p}/3\), for example, a four-photon absorption takes the electron to the continuum. We estimate this ionization in Si:P using the implicit summation method and find that the rate isw= 3.17 s−1forIin= 10 kW/cm2. This ...
the thick (optical) substance blocks more light while the thinner substance blocks less, the layered MoS2 works in an opposite way – the thick (few‐layer) MoS2 allows light transmit (i.e., saturable absorption), while the thinnest (monolayer) MoS2 absorbs more light (two‐photon absorption...
