Laser Atomic Emission Spectrometer with Achromatic Optical System
Abstract
We developed and manufactured a laser atomic emission multichannel spectrometer (LAEMS) with an achromatic optical scheme for research and educational purposes. The new spectrometer fits all the requirements for equipment for laser-induced breakdown spectroscopy and also has a number of advantages due to the design and technical characteristics of its components. As an excitation source, the spectrometer includes two Nd:YAG lasers pumped by semiconductor laser diode arrays, with adjustable energy (from 0 to 100 mJ) and pulse interval (from 1 to 100 ps); the average pulse duration ≈15 ns. LAEMS permits to carry out studies using both single-pulse and double-pulse laser ablation and excitation of emission spectra. Using double pulse laser ablation on LAEMS, a significant (up to 10 times) increase in the analytical signal was recorded, with a slight (1.5-2 times) increase in the surface destruction.
