Hollow-core photonic crystal fibers (HC-PCF) are used for high power beam delivery and can deliver ultra-short or compressed pulses at 1550 nm. This paper study the relation between the length of (9 &7) cell HC-PCFsand the full width at half maximum (FWHM) using laser source with centroidwavelength of 1546.7 nm, i.e. almost 1550nm, and FWHM of 286 pm or 10 ns in the time domain.The FWHM in the frequency domain was increased in both (19&7) cell HC-PCFs as the length of Fabry-Perot interferometer increased till it reachesa specific length and then dramatically decreasedto go to the almost same starting point.
