We focus on difference frequency generation of ultraviolet radiation from two short x-ray pulses by measuring the depletion of the pumping pulses. Like other processes invoking nonlinear interactions between x-rays and longer wavelengths, our method can lead to the development of a probe for ...
Ultraviolet radiation is one section of the electromagnetic spectrum. The range of wavelengths for ultraviolet radiation are between 400 nm - 10 nm. Ultraviolet radiation is divided into subsections, which have different applications. Ultraviolet radiation at wavelengths below or around ...
We present an experimental demonstration of sum-frequency generation toward tunable picosecond, broadband radiation pulses in the extreme-ultraviolet regime, supported by adiabatically prepared atomic coherences. We drive a two-photon transition in a dense medium of xenon atoms with a long (nanosecond)...

This paper describes a new intracavity frequency doubling technique suitable for generating high-power continuous-wave (CW) ultraviolet (UV) radiation. By combining elliptical focusing with a beta barium borate crystal, multi-watt CW deep UV can be obtained in intracavity doubling of an argon ion ...
1.An arrangement of electromagnetic radiation by frequency and wavelength. As a whole, the electromagnetic spectrum ranges from radio waves to gamma rays. The visible spectrum is a band of colors seen when white light is broken up according to wavelengths, as when passing through a prism or str...

Infrared spectra are usually plotted as percent transmittanceTor absorbanceAon a scale linear in wave number &ngr; (less commonly, in wavelength λ). Transmittance is the ratio of the intensity of radiation transmitted by the sample (I) to that incident on the sample (I0), expressed as a pe...
A common method of obtaining indefinite permittivity is to form a structure containing two types of materials, one with a positive permittivity and one with a negative one. If the details of the structure are of dimensions significantly smaller than the radiation wavelength, one can consider the ...
