Polarization dependent electrostrictive grating measurements

The laser induced grating spectroscopy experiments were performed with different polarizations of 1064 nm laser pump beams. Thermal and electrostrictive gratings were observed in the mixture of nitrogen at high pressure with methanol vapor. Suppression of gratings by a continuous change of pump beam...

Description
Summary:The laser induced grating spectroscopy experiments were performed with different polarizations of 1064 nm laser pump beams. Thermal and electrostrictive gratings were observed in the mixture of nitrogen at high pressure with methanol vapor. Suppression of gratings by a continuous change of pump beam polarizations was verified both theoretically and experimentally. Odd and even peaks of the registered signal were found to be responsible, respectively, for electrostrictive and thermal gratings in gas media.
