Abstract

High speed optical measurements in the picosecond regime play a crucial role in any laser .fusion program. At KMS Fusion,image converter streak cameras have been used to study a high power neodymium glass laser system and to observe target response to the laser pulse. Experimental techniques and results ©I several studies will be discussed. A "pulse stacker" produced the desired pulse shape in 30 psec steps. These stacked trains were monitored at various points along the laser system. Perturbations of the pulse train as it propagates through the laser are most evident at the final output where examples of pulse splitting and breakup, which occur in extreme situations, will be shown. Target diagnostic studies include incident and nonabsorbed laser energy pulse shape and blast-wave photographs to determine absorbed energy.
