To observe the effect, a periodically moved external mirror has been used. The periodical changes of the optical beam intensity in the laser cavity generated changes in frequency and amplitude of the acoustic signal. In conclusion, the acoustic wave gives information about optical effects created in a waveguide CO2 laser.}, title={Acoustic mapping of the back-scattering interferometer signal in a CO2 laser}, type={artykuł}, keywords={optyka, CO2 laser, self-mixing, optical feedback, back-scattering, interferometer, photoacoustics}, }
