Single-grating monochromator for extreme-ultraviolet ultrashort pulses.
Extreme-ultraviolet high-order-harmonic pulses with 1.6·10(7) photons/pulse at 32.5 eV have been separated from multiple harmonic orders by a time-preserving monochromator using a single grating in the off-plane mount. This grating geometry gives minimum temporal broadening and high efficiency. The pulse duration of the monochromatized harmonic pulses has been measured to be in the range 20 to ...
متن کاملA stigmatic ultraviolet-visible monochromator for use with a high brightness laser driven plasma light source.
Laser driven plasma light sources offer highly intense output in the UV-visible region combined with a source size as small as 100 μm. In order to effectively use the small source size in high brightness applications, a stigmatic monochromator and focusing system must be used. Here we describe a simple brightness preserving optical system that should be useful across a broad range of applicatio...
متن کاملDesign of an extreme-ultraviolet monochromator free from temporal stretching.
High-order harmonic generation in gases by use of femtosecond lasers is a source of ultrashort pulses in the extreme-ultraviolet (XUV). For many applications it is necessary to select radiation of only one specific harmonic order without affecting the duration of the ultrashort pulse. A three-grating monochromator that meets this demand has been designed and modeled by ray tracing as well as by...
متن کاملHigh-energy-resolution monochromator for aberration-corrected scanning transmission electron microscopy/electron energy-loss spectroscopy.
An all-magnetic monochromator/spectrometer system for sub-30 meV energy-resolution electron energy-loss spectroscopy in the scanning transmission electron microscope is described. It will link the energy being selected by the monochromator to the energy being analysed by the spectrometer, without resorting to decelerating the electron beam. This will allow it to attain spectral energy stability...
متن کاملMonochromator for Aberration-Corrected STEM
In a scanning transmission electron microscope (STEM), the elemental analysis at atomic resolution is realized by the combination with electron energy-loss spectroscopy (EELS), since an aberration corrected probe forming lens system enables us to obtain an electron probe sized about 0.1 nm [1]. In EELS, the energy resolution is mainly limited by the energy spread of the electron source, which i...
