Mass spectrometry - Wikipedia
A mass spectrum is a type of plot of the ion signal as a function of the mass-to-charge ratio. These spectra are used to determine the elemental or isotopic signature of a sample, the masses of particles and of molecules, and to elucidate the chemical identity or structure of molecules and other chemical compounds.
Widely tunable compact terahertz gas lasers | Science - AAAS
Nov 15, 2019 · We introduce a compact, widely frequency-tunable, extremely bright source of terahertz radiation: a gas-phase molecular laser based on rotational population inversions optically pumped by a quantum cascade laser.
Gas Lasers A gas laser contains atoms or molecules. Stimulated transitions occur in atoms between electronic states and in molecules between rotational, vibrational or elec-tronic states. We describe various gas discharge lasers: helium–neon laser; metal vapor laser; argon ion laser; excimer laser; nitrogen laser; CO 2 laser; and optically ...

11.2.3.1: Gas Lasers - Chemistry LibreTexts
Oct 17, 2022 · Analytical Sciences Digital Library. Examples of gas lasers include helium-neon (HeNe), nitrogen and argon-ion. The gain medium in these lasers is a gas-filled tube. Excitation of gas molecules is achieved by the passage of an electric current or discharge through the gas.
Laser absorption spectrometry - Wikipedia
Laser absorption spectrometry (LAS) refers to techniques that use lasers to assess the concentration or amount of a species in gas phase by absorption spectrometry (AS). Optical spectroscopic techniques in general, and laser-based techniques in particular, have a great potential for detection and monitoring of constituents in gas phase.
