Paper Abstract

The automated IR-spectrometer based on the pulsed tunable (1.5 divided by 3.7 micrometers ) optical parametrical oscillator with a spectral resolution of 3 cm-1 and the optothermal phase-contrast detection system is created. A minimal detectable absorption level is as small as (alpha) equals 10-6 cm-1 at the heating energy of 10 mJ.
