The spectrum of barium above the first ionization potential is significantly modified by collisions with rare gas atoms. Atomic Ba vapor was produced in a heat-pipe oven. The two …
Femtosecond (fs) laser propagation and fluorescence of dense potassium vapor was studied, and the spectral region around the first and the second doublets of the principal …

We studied the signal from a thermionic diode when a femtosecond laser beam was spatially overlapped by an excimer pumped dye laser beam. The nanosecond dye laser was …
