BISAC TEC019000 Lasers & Photonics
The photo-acoustic method is widely used to study spectra of linear and nonlinear absorption of the laser radiation by molecular gases and laser gas analysis. In this report the results of the long-term program of the development of the photo-acoustic detectors (PAD) family started in IAO SB RAS in 1972 year are presented for the different types of laser spectrometers and gas- analyzers like: PAD with gas continuum pumping, PAD with Helmgolz and ring resonator, PAD with temporal and space resolution. The summary of specifications of the developing high-sensitive PADs and the PA spectrometers and gas – analyzers is presented together with the review of the experimental results.
