    "abstract": "To meet the strain sensitivity requirements [1], [2] of the Laser\nInterferometer Gravitational Wave Observatory (LIGO), the laser frequency and\namplitude noise must initially be reduced by a factor of 1000 in the\npre-stabilized portion of the interferometer [3]. A control system was\nimplemented to provide laser noise suppression, data acquisition interfaces,\ndiagnostics, and operator control inputs. This paper describes the VME-based\nanalog and digital controls used in the LIGO Pre-stabilized Laser (PSL).",
