Stark Shift of the 6s^{2 1}S₀–6s6p ³P₁ Transition in Ba I

Stark Effect in Two-Electron Atoms by High-Resolution Diode-Laser Spectroscopy

“…The experimental setup is essentially identical to that used in our previous studies [10][11][12]. A laser beam with a power of about 20 mW and a wavelength range of 755-784 nm was obtained from a commercial tunable diode laser with an external cavity system (Sacher Lasertechnik, TEC500).…”
