摘要: A method for fabrication of substrate having a nano-scale surface roughness is presented. The method comprises: patterning a surface of a substrate to create an array of spaced-apart regions of a light sensitive material; applying a controllable etching to the patterned surface, said controllable etching being of a predetermined duration selected so as to form a pattern with nano-scale features; and removing the light sensitive material, thereby creating a structure with the nano-scale surface roughness. Silanizing such nano-scale roughness surface with hydrophobic molecules results in the creation of super-hydrophobic properties characterized by both a large contact angle and a large tilting angle. Also, deposition of a photo-active material on the nano-scale roughness surface results in a photocathode with enhanced photoemission yield. This method also provides for fabrication of a photocathode insensitive to polarization of incident light.

摘要: The microscope (10) includes such main constructional parts as a light source assembly (12); and an optical system (16) configured according to the invention, and in the present example of microscope (generally imaging) system configuration includes also a detection unit (14) (shown in the figure in 5 dashed lines). The detection unit (14) may be configured to define an array of image pixels (e.g. CCD), may be configured for intensified or not intensified light detection, as well as for gated or not-gated light detection. It should be understood that the light source, as well as the detector, may or may not be accommodated in the same housing (15) enclosing the optical path of an input pulse of an initial profile, and system (16). For example, the light source and/or detector may be accommodated outside the housing (15) and light may be guided towards and/or away from a sample S via light guiding means (either in free space or in optical fibers).

摘要: A method and system (10) are presented for producing exciting radiation (P′) to be used in producing an output coherent anti-stokes Raman scattering (CARS) signal of a medium (12).
