Curve-fitting method for pure spectrum measurement of femtosecond laser pulses by a pinhole pair.
We present a curve fitting method for measuring the spectral distribution of femtosecond laser pulses with Young's double-pair interference. The method is applicable to cancel the influence of the mutual coherent portion in the spectrum measurement.
