Abstract

We investigate the enhanced absorption properties in a wavelength range of 0.2-25 μm for NiTi alloy targets structured by femtosecond laser pulses in air. Three different types of surface structures are produced with varying laser fluences. Measured reflectances through integrating sphere technique show that their couplings of incident electromagnetic irradiations are improved greatly over the broadband wavelength range. In particular, for coral-like micro-structures on the metal surfaces, approximate 90% absorption can be achieved from ultraviolet to mid-infrared region. Cut-off wavelengths of the enhanced absorption for the varied dimensional surface structures are determined experimentally. Chemical analysis by X-ray photoelectron spectroscopy indicates that blackness of metal surfaces is not attributed to the change in elemental composition. The physics of such remarkable absorption for the structured metal surfaces are discussed as well.

Fig. 1.

Surface morphologies of the NiTi alloy plates irradiated by femtosecond lasers with three different laser fluences. (a) and (b) for 80 J/cm2, (c) and (d) for 2 J/cm2, (e) and (f) for 20 J/cm2. E is the direction of the laser polarization. S is the direction of the sample scan.

Fig. 2.

Measured integrated reflectance spectra for different surface structures induced by femtosecond lasers on the NiTi alloy plates. (a) in the UV-infrared range of 0.2–2 μm; (b) in the mid-infrared range of 2.5–25 μm. Among them, blue curves are for grating-like structures, olive ones for cellular-like structures, red ones for coral-like structures, and black ones for the polished metallic substrates without any laser treatments. Cut-off wavelengths of the enhanced absorption for different surface structures are marked by arrows in (b).
