Abstract
Two-photon excited laser-induced fluorescence (LIF) spectra of argon atom were successfully observed in a Grimm-style glow discharge tube, which has widely been applied to depth profiling of the elemental composition on various film-like samples by emission spectrometry. The LIF signal of an argon atomic line at 641.63nm was observed when the glow discharge argon plasma was illuminated by a pulsed Ti:sapphire laser radiation of 7-10mJ/pulse at 753.39 or 795.66nm without focusing of the laser beam.
