摘要：

Phase-conjugate emission by resonant degenerate four-wave mixing with two counterpropagating weak pump beams and a noncollinear strong object beam was calculated for a Doppler-broadened two-level system. Single-peak Doppler-free lines with small saturation broadening at a collinear configuration became split for a wide angle. The effect is demonstrated with the use of a CO2 laser and SF6. Conversely, calculated line shapes with Stark splitting in a collinear arrangement became single peaked for a wide angle.
