摘要： A metal or metal alloy including a region with hierarchical micro-scale and nano-scale structure shapes, the surface region is super-hydrophobic and has a spectral reflectance of less than 30% for at least some wavelengths of electromagnetic radiation in the range of 0.1 μm to 10 μm. Methods for forming the hierarchical micro-scale and nano-scale structure shapes on the metal or metal alloy are also described.

摘要： Embodiments of the present invention are generally directed to materials processing methods using femtosecond duration laser pulses, and to the altered materials obtained by such methods. The resulting nanostructured (with or without macro- and micro-structuring) materials have a variety of applications, including, for example, aesthetic applications for jewelry or ornamentation; biomedical applications related to biocompatibility; catalysis applications; and modification of, for example, the optical and hydrophilic properties of materials including selective coloring.

摘要： An optical coating includes a first resonator with a broadband light absorber. A second resonator includes a narrowband light absorber which is disposed adjacent to and optically coupled to the broadband light absorber. The phase of light reflected from the first resonator slowly varies as a function of wavelength compared to the rapid phase change of the second resonator which exhibits a phase jump within the bandwidth of the broadband light absorber. A thin film optical beam spitter filter coating is also described.
