Abstract

High z materials can produce large amounts of x-rays in laser plasma interactions. The efficiency of this process depends on the average intensity and wavelength of the laser light.1 We have demonstrated that the detailed intensity distribution of the laser focal spot is also an important factor in determining the x-ray conversion efficiency. An increase in the low energy x-ray yield from gold targets was noted when induced spatial incoherence (ISI)² was used to provide a smooth spatial laser intensity distribution when compared to a nominal high powered laser focal intensity distribution.
