在grimm型辉光放电管中成功地观察到了氩原子的双光子激发激光诱导荧光（LIF）光谱，该光谱已广泛应用于各种薄膜样样品的发射光谱深度分析。在不聚焦的情况下，用7 ~ 10 mJ/脉冲脉冲Ti：蓝宝石激光照射辉光放电氩等离子体，在753.39和795.66 nm处观察到641.63 nm处氩原子线的LIF信号。
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 641.63 nm was observed when the glow discharge argon plasma was illuminated by a pulsed Ti:sapphire laser radiation of 7–10 mJ/pulse at 753.39 or 795.66 nm without focusing of the laser beam.
