Abstract
This work reports the investigation of low-energy, eye-safe laser-induced breakdown spectroscopy (LE-LIBS) feasibility for in situ detection of gaseous elements significant to the planetary surface chemistry. A ns-pulsed laser emitting pulses of energy of 3 mJ at 1.54 μm wavelength is used to ablate soil pellet samples. Plasma emission spectra are acquired in the spectral window of 220-800 nm employing a concave flat-field spectrograph. Results presented here for the detection of three crucial elements, namely, hydrogen, helium, and oxygen, have demonstrated the applicability of the LE-LIBS approach in a vacuum environment, suiting the planetary surface exploration.
期刊介绍：
The Optical Society (OSA) publishes high-quality, peer-reviewed articles in its portfolio of journals, which serve the full breadth of the optics and photonics community.
Optics Letters offers rapid dissemination of new results in all areas of optics with short, original, peer-reviewed communications. Optics Letters covers the latest research in optical science, including optical measurements, optical components and devices, atmospheric optics, biomedical optics, Fourier optics, integrated optics, optical processing, optoelectronics, lasers, nonlinear optics, optical storage and holography, optical coherence, polarization, quantum electronics, ultrafast optical phenomena, photonic crystals, and fiber optics. Criteria used in determining acceptability of contributions include newsworthiness to a substantial part of the optics community and the effect of rapid publication on the research of others. This journal, published twice each month, is where readers look for the latest discoveries in optics.
