摘      要：The presence of pulse front tilt(PFT),caused by angular dispersion(AD)in femtosecond laser pulses,could degrade the performance of the laser system and/or impact the experimental *** present a single-shot diagnostic capable of measuring the AD in the x–y plane by adopting an intensity *** can be applied to stretched pulses,making it ideal for diagnosing the AD along the amplification chain of a high-power laser system,and to ultrashort pulses exiting from an optical *** this way,it can help in properly characterizing a laser pulse before it is delivered to the target *** this Letter,we present experimental evidence of AD retrieval for different compression configurations,supported by theoretical analysis.
