    "abstract": "We present two experiments in closed-loop feedback control. In the first\nexperiment, students control the pointing angle of a laser to \"lock\" the laser\nonto a \"target.\" In the second, students stabilize the pathlength difference in\ntwo arms of a Michelson interferometer. These experiments are appropriate for\nelectronics and optics laboratory classes for junior and senior level students.",
