Abstract

We present research on the stimulated radiation of duster and new excimers, including their ions, in the VUV/XUV range. Our primary experimental results relate to the stimulated radiated spectra of Heu* at 601 nm and of Aru* at 125 nm. Our experimental setup includes an inert-gas beam chamber with one or two linear-slit nozzles, two electrodes, a cooling trap, and an elliptical mirror. The beam chamber is connected to a Roland-grating spectrometer and a detector chamber with a CEM or a MCP detector in higher vacuums. Our setup could offer a large excited population of 1012 cm-8 in principle, but according to the signal we obtained in the experiments, an excited population of only 1012–1013 cm-3 was found. The reasons for this, a method tor improvement, and other possibilities for lasing at the short wavelengths from the other cluster or duster ions are discussed.
