“…Similar periodic surface structures with ripples, called laser induced periodic surface structures (LIPSS), were seen in short-pulsed laser experiments on mostly crystalline wide band-gap materials [20,21,22]. Those structures also exhibit bifurcations, bends and break-ups, as is seen in the case here.…”

This is the unspecified version of the paper.This version of the publication may differ from the final published version. Permanent repository link ABSTRACTPeriodic surface structures have been observed on the end surfaces of synthetic silica fibres when they are exposed to long-term irradiation with light from a 405 nm CW diode laser. The surface structures are generated when the laser power is at a level which is three magnitudes of order lower than that of the damage threshold. They exhibit multiple bends, break-ups and bifurcations, unlike interference patterns but rather like the effect caused by short-pulsed laser irradiation on wide band-gap insulators. The detailed investigation undertaken in this work has concluded that the key parameters that contribute to the generation of the surface structures are power density, surface roughness, polarisation direction and the presence of ultraviolet defect centres.

“…Some authors called this type of laser induced relief as "anomalous" [10] or "extraordinary" [6,11], because of its allegedly atypical orientation. Previously, RAP were obtained on the dielectric or semiconductor surfaces such as Ge [5,8] and glass [11]. In the case of Ti samples, the appearance of RAP is always accompanied by transformation of surface from metal to dielectric state [1,18].…”

“…This temperature distribution initiates processes responsible for deepening the relief profile: deformation of surface, melting and evaporation of surface material, possibly, capillary waves on the molten surface or surface acoustic waves [6,7,10]. Sometimes, formation of several overlapping relief structures occurs [5][6][7][10][11][12]. In this case, the number of induced surface waves corresponds to the quantity of periodic structures.…”

“…Initially, Fröhlich and Sack [13] established the condition later confirmed by other authors [14] that ppolarized light stronger interacts with electron plasma in the sample than s-polarized light. In general, the laser induced ripples are transverse to the polarization (RTP) of incident light [4][5][6][7][10][11][12]. It was recently shown that femtosecond laser pulses allow obtaining several new types of structures with combined nano-and microstructuring [1,3,[15][16][17][18][19].…”

Abstract. Wavelength-scaled periodic ripples formed on the Ti surface under the action of femtosecond laser irradiation have been investigated. The ripples were oriented in parallel to the incident light polarization. After initial formation of ripples, the following laser induced chemical transformation of metallic Ti into dielectric compound was established using the Raman scattering data. Weak Wood's anomaly in the spectra on light diffracted by the structured Ti surface testifies the minor plasmonic activity.
