Abstract

Evanescent wave spectroscopy measurements were performed using unclad silver halide fibers and tunable laser sources such as lead salts diode lasers and a CO2 laser. Spectra of liquids and gases were recorded. The system S/N ratio and resolution were better than those of FTIR spectrometers. This demonstrates the potential use of tunable lasers in fiberoptic evanescent wave spectroscopy.
