We demonstrate a simple and robust passive coherent combining technique for temporal compression of millijoule energy laser pulses down to few-cycle duration in gas-filled hollow fiber. High efficiency is achieved by using carefully oriented calcite plates pulse division recombination. Carrier-envelope phase (CEP)-stable, 6-fs, 800-nm with more than 0.6 mJ are routinely generated. This method could aid the scaling CEP-stable hollow-fiber compressor systems.
