By definition, the wavelength is the distance between two successive waves (can be trough or crest) and frequency is the number of occurrence of waves in a specified time period. The electromagnetic waves, including the ultraviolet photon mentioned ...
Controlling the side growth of the domain inverted region during high-voltage pulse application, a uniform nonlinear grating with a period of 1.7 μm and 50% duty cycle was fabricated over 10 mm interaction length in a 150 μm thick LiTaO 3 substrate. A 342 nm wavelength of harmonic ...
What colour of visible light has longest wavelength? What is the frequency of ultraviolet light that has a wavelength of 338.3 nm? Which of the following lights has the longest wavelength and the highest frequency and why? a) red light b) blue light c) violet light d...
The wavelength dependence of some of the effects of ultraviolet radiation on the physicochemical properties of DNA of phage α irradiated in vitro are discussed. An analytical ultracentrifuge and a spectrophotometer were used to study ( a) the breaking of individual polynucleotide strands; ( b) the...
(～148nm).The shortest wavelength we can reach is ～55nm.The coherence of the generated light is tested with an optical-heterodyne-based measurement of the third harmonic.The resulted line width is ～3 Hz.In addition,with this system,we also observe a strong suppression of below threshold ...
Just make sure that they filter out both UVA and UVB waves, like your sunscreen. By shell4life — On May 24, 2012 I never knew that the wavelength of ultraviolet waves was so short. When I picture short waves penetrating the air, I imagine that they emit a high-pitched frequency ...
In this work the generation of a high power frequency comb in wavelength regions down to 40 nm via intracavity HHG was demonstrated. The average power around 61 nm (13th harmonic) was close to 1μW (a 105 fold improvement over first generation sources) which made it the most powerful XUV...

s center frequency (Supplementary InformationSI, Section1and Supplementary Fig.1). This property, along with the efficiency of the nanophotonic waveguides, permits us to directly generate comb lines in the ultraviolet from a telecom-wavelength electro-optic source, within a certain bandwidth around ...
An additional, short (picosecond) probe laser pulse at a wavelength of 540 nm beats with the maximal atomic coherence and generates a short (picosecond) signal radiation pulse at 93 nm. As compared to conventional (diabatic) frequency conversion, the adiabatically driven maximal atomic coherence ...
