Research topics
Present activity at the laboratory of laser spectroscopy is focused on application of ultrasensitive laser absorption spectroscopy methods for detection of trace gases in air. Cavity Ring-Down Spectroscopy (CRDS) and Multipass Spectroscopy (MUPASS) are used.
Sensors of NO, NO2 CO, CH4, NH3 and OCS were elaborated; their sensitivity reaches ppb level. Their possible application concerns investigation of air exhaled from human lungs, since these constituents are the markers of various diseases.
The sensors of formaldehyde and ethane (biomarkers of cancers) are elaborated presently. High sensitivity (~1011 cm-3) detector H2O was constructed for atmospheric physics investigation. It allows water vapor observation in air at the altitudes reaching 40 km.
Cavity ring-down spectroscopy (CRDS)
Cavity Ring-Down Spectroscopy belongs to ultrasensitive techniques of laser absorption spectroscopy. The gas sample is located in optical resonator consisting of the mirrors of very high reflectivity. Laser light is used to determine the resonator quality factor. Such parameter decreases with the losses coefficient (i.e. the absorption) increase. For instance the photon lifetime in the cavity can be measured. A comparison of photon lifetime in empty cavity and the lifetime in presence of investigated gas provides opportunity to determine absorption coefficient of the sample.
Multipass spectroscopy (MUPASS)
Multipass approach also belongs to ultrasensitive techniques of laser absorption spectroscopy. It exploits the light path lengthening in investigated sample. The absorption cell is equipped with two mirrors which are precisely located each in respect to the other. Light beam is introduced to the cell through a small hole in one of the mirror. Due to multiply reflection among the mirrors (tens of even hundreds of times) the beam passes repeatedly through the sample. The effective paths of tens or even hundreds of meters can be achieved in the cell. The absorber concentration is determined using the Lambert – Beer law.
