Xenon ion laser-induced fluorescence using a visible tunable diode laser near 680 nm.

Laser-induced fluorescence (LIF) measurements have been performed for the first time in a low temperature (Te≈0.6eV) Xe plasma using a tunable diode laser in the visible range of wavelengths. The transition in Xe II involved the (P13)5d[3]7∕2 metastable state and the excitation wavelength was found to be 680.570±0.001nm (air). LIF measurements of I2 in a room temperature iodine gas cell were used to monitor the wavelength of the laser during the measurements.
