Outline of Final Research Achievements

We studied about a vacuum ultraviolet laser pumped by low-pressure longitudinal discharge like an excimer lamp. In Xe2* with the wavelength of 172 nm, the characteristics of the singlet emission was investigated using several excitation circuits. The singlet emission has high intensity at the low pressure of about 10 Torr. In a gain measurement, the amplification and/or the absorption were observed but our experimental set up has new problem. Moreover, as new gas lasers using this system, a longitudinally excited N2 laser with the low beam divergence of 0.3 mrad (full angle) and the a longitudinally excited N2 laser pumped by pulse inductive discharge were developed.
