Abstract

The Cavity Ring-Down Spectroscopy system for medical applications is created and first results for detection of acetone are shown. The acetone concentration was measured in the air. In the system a pulsed 1 kHz 266 nm DPSS laser with pulse length of 10 ns is coupled in a gas cell with high reflectivity mirror.

Highlights

  • In the system a pulsed 1 kHz 266 nm DPSS laser with pulse length of 10 ns is coupled in a gas cell with high reflectivity mirror

  • Acetone in human breath gas has been established as a biomarker for type-1 diabetes (T1D) [1] and different other diseases

  • We report in this publication the first measurements of acetone concentration by the Cavity Ring-Down spectroscopy (CRDS) system build in Latvia
