A diode-laser-based spectrometer for in-situ measurements of volcanic gases (2004)

Abstract

We report the first results of the field operation of a novel, portable diode-laser spectrometer for gasconcentration measurements in volcanic areas. Remote detection of direct absorption line shapes was possible thanks to a telecomsingle-mode optical fiber that delivered radiation from a room-temperature distributed-feedback diode laser, emitting at 1.997 µm, to an open-path multiple-reflection cell, placed on gas effluxes. The system was deployed on two different active volcanoes in Italy, where simultaneous and continuous monitoring of CO2 and H2O concentrations has been demonstrated.. published. 235-240
