Research Abstract |
In this study, vacuum ultraviolet absorption spectroscopy system was developed using inductively coupled plasma as a VUV light source. The accuracy of the number density measurement was enhanced more than one order of magnitude combined with the temperature measurement by laser absorption spectroscopy and the measurablerange was expanded to five orders of magnitude using a dual tube ICP source. Finally, the population inversion was realized by pumping the ground state by the ICP light, which shows feasibility of the two stage absorption spectroscopy.
