"Ultracold molecules are poised to open many important applications, ranging from quantum information science to precision tests of fundamental physics. In the past decade, direct laser cooling of molecules has successfully achieved magneto-optical trapping, sub-Doppler cooling, and confinement in conservative optical traps. A key research direction for molecule-based quantum science requires achieving a high phase space density. We have recently demonstrated the highest phase-space density in a bulk gas of laser cooled molecules. We are working on further increasing the phase space density of YO molecules by optimizing the scattering rate of the slowing scheme and MOT parameters. We will present our latest work in this direction and also discuss a scheme to utilize narrow-line cooling on an intermediate low–lying A’2Δ3/2 state, after cooling the YO molecules by gray molasses to a few microkelvin temperature.
