Abstract:
We present a method of analyzing the output of a single pulse of light from a Fabry-Perot interferometer (FPI). Together with an independent measurement of the pulse width and shape, the analysis enables the determination of the linewidth, TBP, and, consequently, the degree of coherence of the individual light pulses. The analysis presented builds on the method presented by Marzenell et al. [Appl. Phys. B 71, 185-191 (2000)] by analyzing the ring pattern of the FPI.
