To measure the pulse width of femtosecond laser rapidly and accurately, a measurement system was designed based on the second order autocorrelation principle. The results show that pulse width of the seed laser at 800nm was 199.51fs tested by the independently designed measurement system and was 217.6fs tested by the single pulse autocorrelation instrument of Coherent company. The error is only 0.43%. The results proved that this independent measurement system can test the femtosecond pulse width precisely.
