We calculate the two-level pump-probe absorption coefficient including both upper-to-lower-level decay and level decays to a still lower-lying reservoir level. The probe-absorption profile can have arbitrary ratios of the natural linewidth and detuning to the Doppler width. We observe and explain new line-shape features that occur when the two main levels decay to the reservoir level at different rates.
