Doppler-free absorption spectra of resonance laser fields are studied upon two-stage excitation of cesium atoms according to the schemes 6S{sub 1/2{yields}}6P{sub 3/2{yields}}6D{sub 5/2} and 6S{sub 1/2{yields}}6P{sub 3/2{yields}}8S{sub 1/2}. The obtained experimental results are in qualitative agreement with the theory. In the case of weak absorption saturation, the width of resonances is mainly determined by two-photon transitions. The efficiencies of the two variants of two-stage excitation of the 7P{sub 3/2} level are compared. The possibility of fabrication of a gas laser operating on the 455-nm 7P{sub 3/2{yields}}6S{sub 1/2} transition with the optical depopulation of the lower operating level by an additional laser is discussed.
