We review laboratory experiments of Laser Tomographic Adaptive Optics (LTAO) and Multi-Object Adaptive Optics (MOAO) on a simulated 10-meter telescope testbed at 710 nm. The system maintains 20-35% Strehl across 45 arcseconds over the equivalent of 0.8 seconds of operation. New results are presented at a variety of simulated wavelengths following a system upgrade to 85x85 subapertures across a 10-meter pupil. The delivered PSF is nearly diffraction-limited at wavelengths as blue as 425 nm.
