Single shot measurement of THz pulses based on pulse front tilting by reflective grating

Summary form only given. A femtosecond pulse with tilted intensity front generated by a reflective grating were used as the probe beam for the single shot measurement of THz pulses with high frequency resolution and low distortion. The time window is up to 20 ps and spectrum range covers 0.1-2.5 THz. The result agrees well with the traditional electrical-optic sampling method.
