We present a method for determining the 2p (in Paschen notation) collisional excitation transfer coefficients in noble gases using continuous-wave laser collisionally induced fluorescence (CW LCIF, i.e. fluorescence from an upper level which is not t

We describe a method for the determination of rate coefficients for collisional excitation out of the 1s states of a noble gas using continuous-wave laser collisionally induced fluorescence (CW LCIF, i.e. fluorescence from an upper level which is not

A rate-equation model with greatly improved quantitative rigour is detailed for the CW optogalvanic effect on the 1s-2p transitions of neon atoms in the positive column of a dc normal glow discharge. This work constitutes one part of a wider compleme

Post ablation ionization (PAI) of neutral atoms from a low alloy steel has been investigated using non-resonant laser ionization in a time-of-flight mass spectrometer. By varying the delay between the ablation and ionization lasers, the velocity dist

Resonant laser ablation (RLA) is a novel surface analytical technique which has been investigated by detecting small quantities of aluminium in NIST SRM steel samples 1263A and 1261A. From the results obtained it has been estimated that detection lev

Laser ablation of solid GaAs samples has been studied using one tunable pulsed dye laser. At relatively low laser power, enhancements of up to several hundred times have been observed in the yield of resonantly ionised Ga using laser wavelengths corr

Resonant laser ablation (RLA) is a technique in which a pulsed tunable laser beam is directed at grazing incidence to the surface of a sample, such that neutral atoms are first ablated and then resonantly ionized by the same pulse. In this short comm

A perturbed steady-state rate-equation model has been developed for the cw laser collisionally induced fluorescence (LCIF) produced by excitation on one of the 1s-2p noble gas transitions. This work is one part of a wider complementary modeling progr
