  We report preliminary results from a targeted investigation on quasars
containing damped Lyman-alpha absorption (DLA) lines as well strong metal
absorption lines, carried out with the Potsdam Multi Aperture Spectrophotometer
(PMAS). We search for line-emitting objects at the same redshift as the
absorption lines and close to the line of sight of the QSOs. We have observed
and detected the already confirmed absorbing galaxies in Q2233+131 (z_abs=3.15)
and Q0151+045 (z_abs=0.160), while failing to find spectral signatures for the
z=0.091 absorber in Q0738+313. From the Q2233+131 DLA galaxy, we have detected
extended Ly-alpha emission from an area of 3"*5".
