Vacuum radiation and frequency-mixing in linear light-matter systems

Generation of vacuum ultraviolet radiation by sum frequency mixing of a femtosecond and a nanosecond laser

Ž . The interaction of high-intensity short pulse fs lasers with atomic or molecular vapors permits the conversion of visible light to intense coherent radiation in the vacuum ultraviolet spectral region. We demonstrate sum frequency mixing of a Ž . Ž . high-intensity short pulse fs laser with a conventional long pulse ns laser to extend the accessible wavelength range of harmonic generation. T...

New Method of Quality Control Test for Light and Radiation Field Coincidence in Medical Linear Accelerators

Introduction: The evaluation of X-ray and light field coincidence in linear accelerators as a quality control test is often performed subjectively, involving the manual marking of films and their visual inspection following the irradiation. Therefore, the present study aimed to develop an objective method for the performance of this test leading to the increased levels...

: metadiscourse in introduction sections of applied linguistics and physics research articles: exploring variation in frequency and type

abstract in written mode of language, metadiscourse markers are used commonly to help writers in general and academic writers in particular to produce coherent and professional texts. the purpose of the present study was to compare introduction sections of applied linguistics and physics articles regarding their use of interactive and interactional metadiscourse markers based on the model pro...
