Abstract
We have discovered two high-redshift (z abs =3.388 and 2.908) damped Lyα absorption systems and a third possible damped system (z abs =3.080) while obtaining spectra of optical counterparts from a sample of flat spectrum radio sources. These three systems all have higher redshifts than any previously known damped Lyα absorption systems in the spectra of radio-loud quasars, and they are among the highest redshift damped Lyα systems known. It is unlikely that we would have found as many as two or three damped Lyα absorption systems among our sample unless there is a significant increase in the area-weighted comoving density of damped systems for z≥3
