Laser Safety: Past and Present Problem Areas
At first thought, one might dismiss the subject of laser safety as deserving little scientific attention. One can find little excitement in arguments over the size, shape, and color of laser warning signs. On the other hand, a closer study of the factors which affect laser hazards reveals a series of multifaceted problems. Hidden behind many of these practical problems are often several very fundamental scientific questions. In these lectures I shall not review practical laboratory laser safety procedures; these may be found in a variety of laser safety pamphlets and in safety standards (e.g., ACGIH, 1976; ANSI, 1976; LIA, 1977). Instead I shall focus on a few interesting problem areas which we faced in deriving safe exposure limits and on some remaining unresolved questions.
