High e+/e− Ratio Dense Pair Creation with 10(21)W.cm(−2) Laser Irradiating Solid Targets

We report results of new pair creation experiments using ~100 Joule pulses of the Texas Petawatt Laser to irradiate solid gold and platinum targets, with intensities up to ~1.9 × 10(21) W.cm(−2) and pulse durations as short as ~130 fs. Positron to electron (e+/e−) ratios >15% were observed for ma...
