    "abstract": "Electro-optical feedback has many features in common with optical\nnonlinearities and hence is relevant to the generation of squeezing. First, I\ndiscuss theoretical and experimental results for traveling-wave feedback,\nemphasizing how the ``in-loop\u0027\u0027 squeezing (also known as ``squashing\u0027\u0027) differs\nfrom free squeezing. Although such feedback, based on ordinary (demolition)\nphotodetection cannot create free squeezing, it can be used to manipulate it.\nThen I treat feedback based on nonlinear quantum optical measurements (of which\nnon-demolition measurements are one example). These {\\em are} able to produce\nfree squeezing, as shown in a number of experiments. Following that I discuss\ntheories showing that intracavity squeezing can be increased using ordinary\nfeedback, and produced using QND-based feedback. Finally, I return to\n``squashed\u0027\u0027 fields and present recent results showing that the reduced in-loop\nfluctuations can suppress atomic decay in a manner analogous to the effect for\nsqueezed fields.",
