In this paper, the spectral behavior of a two-cell phase conjugated mirror (PCM) with a two-pass Nd:YAG amplifier has been analyzed experimentally and theoretically and compared to the conventional mirror. For this purpose, amplifier input intensity for the two different states of laser oscillator with two and more longitudinal modes have been investigated. Results of the Fourier analysis of the amplified intensity show considerable differences between Fourier amplitudes of the amplifier equipped with PCM and a two-pass amplifier with a conventional turning mirror under the same output energy. The amplifier with PCM has a completely filtered and different spectral behavior with clearly reduction of the beating between Fourier components of the input optical field.
