Abstract: We present multi-epoch, multi-wavelength Laser Guide Star Adaptive Optics (LGS AO) observations of the Arches cluster to probe how the properties of emergent stellar populations within our Galaxy may be affected by the physical environment in which they arise. Our multi-epoch LGS AO data set offers two distinct advantages over earlier mass function studies; first, it has higher angular resolution, reducing the impact of source confusion, and second, it provides proper motion measurements, enabling direct identification of cluster members. We apply new data sets and AO point spread function (PSF) extraction tools to present new measurements of the Arches mass function.
