Abstract:
The design, construction, and use of high peak power infrared laser pulses for the generation of diagnostic (20 keV to 150 keV) x-rays are discussed. A review of recent laser-plasma generation of diagnostic x-rays is presented. The advantages of such sources include subpicosecond pulse duration and extremely small source size. Because of their short duration, it shoud be possible to form time-gated medical images with up to eight times less x-ray flux than with conventional x-ray sources. Details of a next generation laser driver are also presented. Generation of 20-fs pulses from a regenerative
