Narrow-Band Extreme-Ultraviolet Laser Radiation Tunable in the Range 90.5-95 nm
Tunable, narrowband extreme ultraviolet radiation in the range 90.5-95 nm with only limited intensity variations is produced by frequency-tripling ultraviolet light from a frequency-doubled dye laser in a gas-jet of xenon, Acetylene gas is found to be an efficient medium for thirdharmonic generation in this wavelength range as well. The extreme-ultraviolet radiation is applied in a spectroscopi...
متن کاملNarrow-band tunable extreme-ultraviolet laser source for lifetime measurements and precision spectroscopy
A narrow-band, extreme-ultraviolet laser source is developed that has continuous tunability in the range 96– 97.5 nm and a bandwidth below 250 MHz. The versatility of the radiation source is demonstrated in two applications. Accurate values for lifetimes of highly excited molecular quantum states are determined from line-broadening measurements in three electronic states of CO: W1P, v 5 0 state...
متن کاملhmb-۴۵ study before and after narrow-band (۳۱۱ nm) ultraviolet b treatment in vitiligo
conclusions the hmb-45 stain strength significantly changed after treatment in perilesional skin. results twenty-nine patients completed the study. the wilcoxon test showed a meaningful relation between hmb-45 staining before and after nb-uvb treatment in perilesional skin. we did not find a meaningful relation between hmb-45 staining before and after treatment regarding the mean age, gender, m...
متن کاملGeneration of Narrow-band, Coherent, Tunable Terahertz Radiation Using a Laser-modulated Electron Beam∗
The technical layout and initial results of an experiment to generate narrow-band, coherent, tunable terahertz (THz) radiation through the down-conversion of the frequency of optical lasers using a laser-modulated electron beam are described. In this experiment, a 120 MeV electron beam is first energy modulated by two lasers with different wavelengths. After passing through a dispersive section...
متن کاملNarrow band Ultraviolet B 311 nm in the treatment of vitiligo: two right-left comparison studies.
AIM Evaluation of narrow band ultraviolet B (NB UVB 311 nm) in the treatment of vitiligo by two independent studies. The first study compared NB UVB with a well-established therapeutic modality, psoralen ultraviolet A (PUVA), and the second study was conducted to find out whether psoralen might add to its efficacy. METHODS In the first study, 15 patients were exposed on the left half of their...
