Abstract
In classical ovens, vapour pressure of small molecules including refractory compounds is generally too weak to undertake their spectroscopic characterization in the gas phase. Laser sources as they allow any material to be vaporized whatever its melting point, bring a satisfactory answer to this problem. We designed a source of this type with the aim to undertake the spectroscopic characterization of small molecules including carbon or nitrogen together with a metal of large astrophysical abundance (Al, Mg, Na, Fe). The first mass spectra of neutral molecules as well as ions produced by this source are presented in this paper.
