5. Conclusions
Mid – IR spectrometer based on AGS OPO and fun - out
PPLN OPO pumped by a 1.053 µm Nd: YLF laser was
demonstrated experimentally. Absorption spectra CH4,
C3H8, C2H6, C2H4 , CO2 and human’s breath were studied
by using tandem OPO-PAD. Probes of real patients
(COPD, tuberculosis, asthma) are studied.
We were demonstrating new perspectives of using
photo-acoustic spectroscopy for noninvasive medical
diagnostics. Compact analytical systems for different
applications can be developed with use of this approach.
