| 1. | It has been shown that when the partially coherent beams propagate in the atmosphere , it may be less affected by turbulence than are fully coherent ones . moreover in laser fusion a highly coherent beam is transformed into a partially coherent beam , for reducing the speckle and for getting more smooth focused spot
例如,部分相干光在大气中传输时所受大气骚动的影响要比完全相干光小得多;并且部分相干光束具有光强比较均匀,对散斑低灵敏等优点而被应用于激光核聚变等领域。 |
