“…While the periods of LIPSS generated in air and vacuum are quite similar, the irradiation in liquids usually leads a) to a significant reduction of the LIPSS periods to values as small as $100 nm. [36][37][38] However, for practical applications, processing in air is strongly desirable in order to avoid expensive equipment and reducing the processing time and production costs. In this contribution, we address the current research state in this field of LIPSS generated by fs-laser pulses in air.…”

The formation of laser-induced periodic surface structures (LIPSS) in different materials (metals, semiconductors, and dielectrics) upon irradiation with linearly polarized fs-laser pulses (τ ∼ 30–150 fs, λ ∼ 800 nm) in air environment is studied experimentally and theoretically. In metals, predominantly low-spatial-frequency-LIPSS with periods close to the laser wavelength λ are observed perpendicular to the polarization. Under specific irradiation conditions, high-spatial-frequency-LIPSS with sub-100-nm spatial periods (∼λ/10) can be generated. For semiconductors, the impact of transient changes of the optical properties to the LIPSS periods is analyzed theoretically and experimentally. In dielectrics, the importance of transient excitation stages in the LIPSS formation is demonstrated experimentally using (multiple) double-fs-laser-pulse irradiation sequences. A characteristic decrease of the LIPSS periods is observed for double-pulse delays of less than 2 ps.

“…In the fs-laser ablation experiment, spontaneous selforganization process has often been observed to produce nanoscale periodic structures on the surface of targets such as dielectrics, [1][2][3][4] semiconductors, [5][6][7] and metals. [8][9][10] The observed nanostructure size is typically 1/10-1/5 of the laser wavelength k. This phenomenon has attracted considerable interest since the first observations a decade ago [1][2][3] because the selforganized surface nanostructure suggests a potential route to transcend the diffraction limit in the laser-matter interactions.…”

“…This condition has been employed in most common to form the periodic surface nanostructure for different kinds of materials. [1][2][3][4][5][6][7][8][9][10][20][21][22][23][24][25][26] We expect that under the condition, the incident fs laser pulse hardly induces strong thermal effects such as thermal melting and erosion before the onset of ablation, and then the ablation trace should be the fingerprint of ultrafast interaction of fs laser pulses with the target surface. The experimental results obtained in our studies support the following scenario of nanostructuring in progress with an increase in the superimposed shot number N of fs laser pulses at a low fluence: 23,27 On a flat target surface, multiple shots of low-fluence fs pulses induce bonding structure change of the material through the linear or nonlinear light absorption.…”

Ablation of solid surfaces irradiated with superimposed multiple shots of low fluence femtosecond (fs) laser pulses often results in the formation of periodic nanostructures on the target surface. We demonstrate that the self-organization process of nanostructuring can be regulated to fabricate a homogeneous nanograting on the target surface in air. A simple two-step ablation process was used to control the nanoscale energy deposition that should be developed through the excitation of surface plasmon polaritons (SPPs) during the fs laser-surface interaction. The results obtained for crystalline gallium nitride represent exactly the nature of a single spatial standing wave mode of SPPs of which periodically enhanced near-fields ablate the target surface to form the nanograting with a period of ∼200 nm. The calculated results for a model target reproduce well the observed nanograting period and explain the origin of its characteristic properties.

“…(3) For the same laser parameters, the performance of ablation in air and that in water for single laser pulse are comparable, but the latter is slightly better than the former. This result conflicts with that for short-pulse laser ablation IALE [1,2]. (4) With the number of laser pulses increasing, ablation in water outperforms that in air, as evidenced by the larger ablation volume, deeper crater height, and more lubricious crater rim.…”

To clarify the role of a natural or artificial liquid environment in the free-running infrared pulsed laser ablation of hard biological tissues, two-and three-dimensional morphologies of laser-induced craters must be quantitatively measured to distinguish ablation differences in air and in water. Full-field optical coherence microscopy is introduced, which has non-contact, non-destructive, non-preprocessing and higher-resolution advantages. Experimental results indicate that the ablation performances in air and in water are comparable for few laser pulses, but the ablation difference becomes obvious for more laser pulses. Optical coherence microscopy is more feasible than conventional means for the morphological measurement of craters. ablation of hard tissue, optical coherence microscopy, holmium laser pulse Citation:Lü T, Xiao Q, Li Z J, et al.
