Recently, preference in medical diagnostics has been given to non-invasive methods. One of the most promising is the analysis of air exhaled by a person. For such a task, it is proposed to use ultraspectral resolution Raman spectroscopy. A spectromet

It is shown that the power consumption in the double-pulse bi-spectral primary source for EUV lithography can be substantially decrease by replacing pre-amplifiers in power CO 2 laser with the SRS converters wavelength 1.06 μm to 10.6 μm while main
