摘要
An optical parametric chirped-pulse amplification system delivering pulses with more than 12 GW peak power is presented. Compression to sub-5 fs, 87 mu J and 5: 4 fs, 100 mu J is realized at the 30 kHz repetition rate. A high-energy fiber chirped-pulse amplification system operating at 1 mJ pulse energy and nearly transform-limited pulses is used to achieve ultrabroadband amplification in two 2 mm beta-barium borate crystals. Precise pulse shaping is used to compress the pulses to a few percentages of their transform limit. Assuming diffraction limited focusing (d < 2 mu m), peak intensities as high as 10(18) W/cm(2) can be reached. (C) 2011 Optical Society of America
