The Autler-Townes effect (also known as ac, optical or dynamical Stark splitting) on the Balmer-{alpha} transition of hydrogen in 0.5--5 torr of helium is investigated. In the double optical resonance scheme, H(3p) is excited by absorption of two 243-nm photons and a 656-nm photon via the 2s resonant intermediate level. Calculated results show that in a Doppler-free or a Doppler-reduced'' beam configuration, the required intensity of the 656 nm laser (0.2 cm{sup {minus}1}bandwidth) for observing the Autler-Townes doublet has to be greater than 2{times}10{sup 4} W/cm{sup 2} and 2{times}10{sup 5} W/cm{sup 2} for a 243-nm laser bandwidth of 0.1 cm{sup {minus}1} and 0.5 cm{sup {minus}1}, respectively.
