The problem of early termination of laser action in flashlamp pumped dye lasers is investigated. It is found that in high power, short pulse duration systems shock waves are created in the dye solution. Index inhomogeneities in the laser medium are created, and these lead to the termination of laser action. The velocity of propagation of the disturbance is measured. Some possibilities concerning the origin of these shock waves are examined. A design scheme that overcomes the effect of the disturbance in short pulse (</=5 microsec) systems is described.
研究了闪光灯泵浦染料激光器中激光作用过早终止的问题。发现在高功率、短脉冲持续时间的系统中，染料溶液中会产生冲击波。激光介质中会产生折射率不均匀性，这些会导致激光作用的终止。测量了扰动的传播速度。研究了关于这些冲击波起源的一些可能性。描述了一种克服短脉冲（≤5微秒）系统中扰动影响的设计方案。
