We present a tomographic cosmic shear study from the Deep Lens Survey (DLS),which, providing a limiting magnitude r_{lim}~27 (5 sigma), is designed as apre-cursor Large Synoptic Survey Telescope (LSST) survey with an emphasis ondepth. Using five tomographic redshift bins, we study their auto- andcross-correlations to constrain cosmological parameters. We use aluminosity-dependent nonlinear model to account for the astrophysicalsystematics originating from intrinsic alignments of galaxy shapes. We findthat the cosmological leverage of the DLS is among the highest among existing>10 sq. deg cosmic shear surveys. Combining the DLS tomography with the 9-yearresults of the Wilkinson Microwave Anisotropy Probe (WMAP9) givesOmega_m=0.293_{-0.014}^{+0.012}, sigma_8=0.833_{-0.018}^{+0.011},H_0=68.6_{-1.2}^{+1.4} km/s/Mpc, and Omega_b=0.0475+-0.0012 for LCDM, reducingthe uncertainties of the WMAP9-only constraints by ~50%. When we do not assumeflatness for LCDM, we obtain the curvature constraintOmega_k=-0.010_{-0.015}^{+0.013} from the DLS+WMAP9 combination, which howeveris not well constrained when WMAP9 is used alone. The dark energy equation ofstate parameter w is tightly constrained when Baryonic Acoustic Oscillation(BAO) data are added, yielding w=-1.02_{-0.09}^{+0.10} with the DLS+WMAP9+BAOjoint probe. The addition of supernova constraints further tightens theparameter to w=-1.03+-0.03. Our joint constraints are fully consistent with thefinal Planck results and also the predictions of a LCDM universe.
