“…This transition has been extensively studied before with the parameters λ = 800 nm and τ D = 1.1 fs, corresponding to γ/ω = 0.39. 9,13,18,23,24 The evolution of the Fourier transforms along both k x = 0 and k y = 0 axes as ω p /ω grows for γ/ω = 1 is shown in Figure 4. These are two orthogonal slices of the correspong two-dimensional calculations of Figures 3(a) -(f).…”

The formation of a new type of laser-induced periodic surface structures using a femtosecond pulsed laser is studied on the basis of the Sipe-Drude theory solved with a FDTD scheme. Our numerical results indicate the possibility of coexisting structures parallel and perpendicular to the polarization of the incident light for low reduced collision frequency (γ/ω 1/4, where ω is the laser frequency). Moreover, these structures have a periodicity of Λ ∼ λ in both orientations. To explain this behavior, light-matter interaction around a single surface inhomogeneity is also studied and confirms the simultaneous presence of surface plasmon polaritons and radiation remnants in orthogonal orientations at low γ/ω values.

“…A possible explanation for this phenomenon might be that the morphology of NPs could be changed by the melting effect. To confirm this, the two‐temperature model is utilized to calculate the electron temperature and lattice temperature of NPs:

C_{e} \frac{\partial}{\partial t} T_{e} = k_{e} \nabla^{2} T_{e} - G_{e l} (T_{e} - T_{l}) + S (r, t)

C_{l} \frac{\partial}{\partial t} T_{l} = G_{e l} (T_{e} - T_{l})

where T e and T l represent the electron and lattice temperatures; C e and C l are the electron and lattice heat capacities; S ( r , t ) is the laser heat density; in the meanwhile, k e and G el denote the electron thermal conductivity and electron–phonon coupling factor, respectively. As shown in Figure 3c, the thermalization between the carrier and the lattice system is reached in 15 ps when the laser fluence is 0.002 J cm −2 .…”

Saturable absorbers are key elements for generation of ultrafast laser pulses. The commercially available semiconductor saturable absorber mirrors are wavelength sensitive and with complex fabrication process and high cost. Fused silica is one of the basic materials for various optical applications. Plasmonic nanoparticles can be used to efficiently modulate the optical properties of dielectric materials owing to the enhanced field effects based on localized surface plasmonic resonance. Ion implantation is a direct technique to synthesize plasmonic nanoparticles inside dielectric materials, which can simultaneously tailor the optical nonlinearity of substrates significantly. In this work, Ag ion implantation into fused silica with tunable interparticle spacing is used to generate broadband optical nonlinearities and to endow silica with ultrafast saturable absorption property. This ion implantation forms a 2D‐like Ag nanoparticle monolayer buried inside fused silica wafer. The fused silica with embedded 2D‐like Ag nanoparticle monolayer is further applied as a new saturable absorber to generate ultrafast laser pulses with pulse duration of 27 ps and repetition rate of 6.5 GHz through the passive mode‐locking process. This work opens up a new route to develop low‐cost, highly stable saturable absorbers, and offers the possibility to build novel silica‐based photonic systems through nanoparticle spacing manipulation.

“…Single-pulse irradiation can provide fundamental information of fs laser-matter interaction, which is important for investigating the origin of an LSFL [18][19][20] . Murphy et al fabricated Au micro-disks 110 nm thick on Si substrates, and studied the formation of periodic ripples near the Au-Si edges after irradiation of a single fs laser pulse.…”

“…By changing the laser polarization orientation, they found that the LSFL formation was dominated by SPPs excitation or by Fresnel diffraction [18,19] . Yang et al studied the generation and erasure of periodic ripples on nanoparticlecovered silicon induced by a single fs pulse with a different laser fluence, and found that these phenomena were due to the competition between periodic surface structuring originated from the interference of the laser field and SPPs and surface smoothing associated with surface melting [20] . The above references focused on the mechanisms of the LSFL formation on semiconductors by using the surface micro/nanostructures as defects after the irradiation of a single pulse.…”

Periodic surface structures on Ni–Fe film induced by a single femtosecond laser pulse with diffraction rings

et al. 2017

This Letter reports the formation of periodic surface structures on Ni-Fe film irradiated by a single femtosecond laser pulse. A concave lens with a focus length of −150 mm is placed in front of an objective (100×, NA ¼ 0.9), which transforms the Gaussian laser field into a ring distribution by the Fresnel diffraction. Periodic ripples form on the ablation area after the irradiation of a single femtosecond laser pulse, which depends on the laser polarization and laser fluence. We propose that the ring structure of the laser field leads to a similar transient distribution of the permittivity on the sample surface, which further launches the surface plasmon polaritons. The interaction of the incident laser with surface plasmon polaritons dominates the formation of periodic surface structures.OCIS codes: 220.4241, 160.3900, 240.6700, 320.7090. doi: 10.3788/COL201715.022201.Laser-induced periodic surface structures (LIPSSs) have been studied intensely in the last five decades [1][2][3][4][5][6][7][8] . Initial reports on the formation of LIPSSs were usually irradiated by a continuous wave (CW) or long duration laser pulses [nanosecond (ns) laser]. The periods of these structures (are usually ripples) were approximately equal to the laser wavelength. These periodic ripples were attributed to the interference between the incident laser and the scattered light caused by surface defects [1][2][3][4] . Low spatial frequent LIPSSs (LSFL) have been observed in semiconductors, dielectrics, and metals after the irradiation of femtosecond (fs) laser pulses . Laser polarization, fluence, and the number of laser pulses have been identified as the key parameters for the LSFL formation. Experimental results indicated that the dynamics of a fs laser-induced LSFL were rather different from the near-wavelength ripples induced by a CW and a ns laser. For a normal incident laser with a wavelength λ, the ripple periods changed in the range of 0.5λ-0.95λ [15]
