Abstract

The contrast and steepness of spectral repers, detected by two nonlinear Doppler free techniques -- photon echo in standing waves (PESW) and saturated absorption spectroscopy (SAS) -- are investigated at 0 yields 1 (nu) ₃ P(33) A₂¹ SF₆ transition for identical experimental conditions (over gas pressure and exciting beams geometry) versus intensity of CO₂ laser radiation. S/N advantage of PESW technique as compared to SAS method is demonstrated. The increasing role of slow molecules in generation of photon echo response at elevated time delays between exciting pulses manifests itself experimentally in slowing down the photon echo decay rate.
