Abstract:

The rapidly advancing field of high power laser technology has created the requirement for new advanced diagnostic systems. Many approaches have been used in the past to obtain pulsed laser wavefront profiles all of which are very time consuming and laborious techniques. A critical review was made of the existing approaches and new technologies and techniques were analyzed for application to the measurement problem. The resulting system used a Hartmann plate sampling approach, along with transfer optics and a silicon-vidicon camera for accomplishing the laser radiation measurement, high-speed signal conditioning electronics and a high-speed digital computerplotter system were used for data acquisition, processing and display. With this system a pulsed laser wavefront can be measured to the required accuracies on a timely basis.
