缺少合适的激光器也许是空军力图发展一种如下系统所面临的最大技术障碍:这种系统能为空军基地和类似的固定设施提供化学战药剂进袭的早期预警。为了发展这种至少在一英里距离以内能够鉴别特定的化学战药剂的定域探测系统,并且测定它们的浓度和运动方向,以及在任一段时间内监测它们的消散情况,美国空军已经拨款给GTE西尔伐尼亚 The lack of a suitable laser may be the Air Force’s biggest technical obstacle to developing a system that will provide early warning of a chemical warfare attack on Air Force bases and similar fixtures. In order to develop such localized detection systems capable of identifying specific chemical warfare agents within a distance of at least one mile and to determine their concentration and direction of motion and to monitor their dissipation over any period of time, the U.S. Air Force has allocated funds to GTE West Lavalia
