Metrological use of intracavity laser spectroscopy

The use of intracavity laser spectroscopy (ICLS), for the quantitative determination of trace elements in materials in various states of aggregation for applied purposes such as metrology was analyzed. ICLS provides much greater sensitivity, increases the reliability of results, and reduces the analysis time. The ICLS method was found to be sensitive, fast, and with good spectral resolution. ICLS was used to record small refraction and absorption coefficients for heterogeneous plasma objects together with the radiation from polyatomic molecules and clusters.
