Simultaneous realization of time and carrier envelope phase synchronization for an ultra-intense few-cycle laser pulse coherent combining system
Coherent combining of several low-energy few-cycle beams offers a reliable and feasible approach to producing few-cycle laser pulses with energies exceeding the multi-Joule level.However, time synchronization and carrier-envelope phase difference (CEP) between pulses significantly affect temporal waveform and intensity of the combined pulse, requiring precise measurement and control.Here, we propose a concise optical method based on phase retrieval of spectral interference and quadratic function symmetry axis fitting to simultaneously measure the time synchronization and CEP between few-cycle pulses.The control precision of our coherent beam combining system can achieve a time delay stability
