Sentences with phrase «vacuum ultraviolet laser»
Abstract: The energy gap of optimally doped Bi2 (Sr, R) 2CuOy (R = La and Eu) was probed by angle resolved photoemission spectroscopy (ARPES) using a vacuum ultraviolet laser (photon energy 6.994 eV) or He I resonance line (21.218 eV) as photon source.

The results show that the gap around the node at sufficiently low temperatures can be well described by a monotonic d - wave gap function for both samples and the... ▽ More The energy gap of optimally doped Bi2 (Sr, R) 2CuOy (R = La and Eu) was probed by angle resolved photoemission spectroscopy (ARPES) using a vacuum ultraviolet laser (photon energy 6.994 eV) or He I resonance line (21.218 eV) as photon source.
Now UC Davis graduate student Zhou Lu, working with professors in the Departments of Chemistry and of Earth and Planetary Sciences, has shown that oxygen can be formed in one step by using a high energy vacuum ultraviolet laser to excite carbon dioxide.
Zhou used a vacuum ultraviolet laser to irradiate CO2 in the laboratory.

A laser in the vacuum ultraviolet range — the Dalian facility will cover 50 — 150 nanometers — «has a soft touch,» he says, making it «the best way to detect molecules and atoms in a gas.»
The Dalian Coherent Light Source, whose completion was announced today in Beijing, has a twist that makes it unique: It is the only large laser light source in the world dedicated to the particular range of short - wavelength light called vacuum ultraviolet, which makes it «a new tool for the detection and analysis of molecules undergoing chemical reactions,» says Alec Wodtke, a physical chemist at the Max Planck Institute for Biophysical Chemistry and the University of Göttingen in Germany..
The other part of the process, as explained in the paper, is using the high harmonic generation process to produce bright spatially coherent beams from a tabletop laser, spanning the range from the vacuum ultraviolet (wavelengths less than 200 nm) to the soft X-ray region of the spectrum (wavelengths less than 10 nm)
