Dynamic two-wave mixing of periodically phase modulated beams in liquids with thermal mechanism of optical nonlinearity for measurements of thermo-optical characteristics and, in particular, of optical absorption is proposed. Unlike conventional “pump-and-probe” technique, the configuration under consideration does not need an additional probe beam. This reduces problems with alignment and ensures an increased output signal, which proves to be proportional to the recorded photo-thermal grating amplitude. The method is illustrated with experiments performed at λ=633 nm using a model sample of acetone dyed with “methylene blue”. Evaluation of the limit sensitivity of the configuration for detection of low optical absorption is also given.
