  We have employed laser guide star (LGS) adaptive optics (AO) on the Keck II
telescope to obtain near-infrared (NIR) images in the Extended Groth Strip
(EGS) deep galaxy survey field. This is a continuation of our Center for
Adaptive Optics Treasury Survey (CATS) program of targeting 0.5<z<1 galaxies
where existing images with the Hubble Space Telescope (HST) are already in
hand. Our AO field has already been imaged by the Advanced Camera for Surveys
(ACS) and the Near Infared Camera and Multiobject Spectrograph (NICMOS). Our AO
images at 2.2 microns (K') are comparable in depth to those from HST, have
Strehl ratios up to 0.4, and FWHM resolutions superior to that from NICMOS. By
sampling the field with the LGS at different positions, we obtain better
quality AO images than with an immovable natural guide star. As examples of the
power of adding LGS AO to HST data we study the optical to NIR colors and color
gradients of the bulge and disk of two galaxies in the field with z=0.7.
