COMPARATIVE STUDY OF LASER ACCELERATION OF THIN FOILS AT WAVELENGTHS 0.44 MM AND 1.3 MM
The acceleration of thin plastic foils irradiated with frequency triplet ((lambda = 0.44 mum) and fundamental (lambda = 1.3 mum) iodine laser light was investigated. Rear side velocities and two-dimensional behaviour of the foils were recorded with a novel 6-frame photographic diagnostic. Core velocities were inferred from calorimetry and X-ray backlighting. Unlike at 1.3 mum, the rear side and core velocities were found to be quite different at lambda = 0.44 mum. An explanation is offered in terms of lack of lateral smoothing at 0.44 mum.
