Whereas exciting progress has been made to beat diffraction in optical spectroscopy [1-8], making a nano-sized laser beam remains challenging due to diffraction spread [9,10]. Using Bethe’s expression for the optical transmission coefficient of a circular hole in a perfect conductor screen of zero thickness [9,11]. T=1024π3a6/27λ4, we found that the transmission of light with a wavelength λ=800 nm through such a circular hole of a radius of 1 nm is about ~2.3 × 10-6. So a decent nanosized laser beam for miniaturization of optical elements is not available. Here we show that coupling Surface Plasmon-Polaritons (SPPs) to appropriate dielectric material can result in fundamentally diffraction-free down-sized, especially nano-sized laser beams. For example, the composite structure Si3N4/Au(44.5nm)/SiO2 (456nm)/(SiO2, Si3N4, SiO2) can achieve a nano-sized laser beam of about half the incoming light intensity. This approach, by transforming the macroscopic laser beams into multiple nano-sized laser beams, holds promise for ultrafast laser imprinting of nanopores for DNA sequencing and other miniature photonic devices in optical signal processing industries.

As you know classical energy sources are oil, natural gas and coal. As it is known, global warming is one of the most effective problems in recent years. Global warming, which threatens the world, is the classical energy sources we know. At the beginning of these are oil. As a con-sequence of the depletion of fossil fuel reserves, some scientists are exploring alternative energy sources for these energy sources, looking for alternatives to global warming and the depletion of fossil fuel reserves. Fuel price hikes also have an important effect on this research. Some energy sources, which are found in nature, are sources that act at a minimum level of clean, renewable and global warming.
