  We report the first results of our systematic search for strongly lensed
quasars using the spectroscopically confirmed quasars in the Sloan Digital Sky
Survey (SDSS). Among 46,420 quasars from the SDSS Data Release 3 (~4188 deg^2),
we select a subsample of 22,683 quasars that are located at redshifts between
0.6 and 2.2 and are brighter than the Galactic extinction corrected i-band
magnitude of 19.1. We identify 220 lens candidates from the quasar subsample,
for which we conduct extensive and systematic follow-up observations in optical
and near-infrared wavebands, in order to construct a complete lensed quasar
sample at image separations between 1'' and 20'' and flux ratios of faint to
bright lensed images larger than 10^{-0.5}. We construct a statistical sample
of 11 lensed quasars. Ten of these are galaxy-scale lenses with small image
separations (~1''-2'') and one is a large separation (15'') system which is
produced by a massive cluster of galaxies, representing the first statistical
sample of lensed quasars including both galaxy- and cluster-scale lenses. The
Data Release 3 spectroscopic quasars contain an additional 11 lensed quasars
outside the statistical sample.
