Complex molecular structure demands customized solutions to laser cooling byextending its general set of principles and practices. Yttrium monoxide (YO)has unique intramolecular interactions. The Fermi-contact interaction dominatesover the spin-rotation coupling, resulting in two manifolds of closely spacedstates, with one of them possessing a negligible Land\'e g-factor. This uniqueenergy level structure favors dual-frequency DC magneto-optical trapping (MOT)and gray molasses cooling (GMC). We report exceptionally robust cooling of YOat 4 $\mu$K over a wide range of laser intensity, detunings (one andtwo-photon), and magnetic field. The magnetic insensitivity enables the spatialcompression of the molecular cloud by alternating GMC and MOT under thecontinuous operation of the quadrupole magnetic field. A combination of thesetechniques produces a laser-cooled molecular sample with the highest phasespace density in free space.
