　　Based on optical pulses interference.a novel method is proposed for measurement of laser coherence length.The experimental system includes a fiber Mach-Zehnder interferometer (MZI) with the PZT-assisted phase shifter.Our result is closed to that measured by the optical spectrometer.And the partial coherence of the laser pulses has been observed in the experiment.
