KOYO 		High power lasers whose pulse duration is of the order of 1 nanosecond used for inertial confinement fusion studies. These are some of the older generation of lasers such as the NOVA at Lawrence Livermore National Laboratories (NOVA has been recently retired). The following table is sorted by decreasing power.
