TLDR
In this paper, it was shown that circularly polarized light can induce surface ripples, with the damage structure showing a dependence on the sense of rotation, and time resolved results of the formation of the ripples to illustrate the essential dynamical processes that occur.Abstract:
Laser induced periodic surface structure can be understood as a universal phenomenon which occurs when high intensity pulses are absorbed near the surface of solids or liquids. The phenomenon occurs on metals, semiconductors and insulators because of the interference between the incident pulse and an induced “radiation remnant”. This scattered field may be enhanced by the existence of true surface modes such as surface plasmons or phonon-polaritons but this is not essential. The universality characteristics include beam polarization, since we show that circularly polarized light can induce surface ripples, with the damage structure showing a dependence on the sense of rotation. We also present time resolved results of the formation of the ripples to illustrate the essential dynamical processes that occur.read more

Laser mirror damage in germanium at 10.6 μm
TL;DR: In this paper, the germanium output mirror of a TEA CO2 laser shows a periodicity of 10.6 μm, the laser wavelength, and an interference mechanism is proposed in which scattered and cavity radiation interfere.

Stimulated Surface-Plasma-Wave Scattering and Growth of a Periodic Structure in Laser-Photodeposited Metal Films
TL;DR: In this paper, the authors show that the intensity variation due to interference between the incident laser field and the surface-plasma wave modulates the film growth rate, which in turn enhances the scattering of the incident field into the surface plasmas wave; an exponentially growing instability results.
